Asahi Optics Launches the ASEL AO20 & CMB Series Extrusion Linear Lenses

In the world of modern architectural and retail design, the line of light has become a fundamental language. From sleek office corridors to sophisticated retail shelving, linear lighting defines space and directs the human eye. However, for years, designers have struggled with the limitations of traditional injection-molded lenses—specifically the unsightly seams, light leakage at joints, and the cluttered aesthetic of exposed LEDs when the fixtures are turned off.

Unlike injection molding, which is restricted by fixed mold sizes, the extrusion process allows for continuous, uninterrupted runs of optical lenses. By producing lenses in virtually any length, we eliminate the gaps that cause light spill and visual interruptions, ensuring a flawless, unbroken ribbon of light that integrates seamlessly with the architectural environment. Moreover, the extrusion profile acts as a sophisticated mask, elegantly concealing internal PCBs and LED beads even when the power is off, maintaining a clean, high-end aesthetic.

Asahi Optics understands that a perfect linear system requires the harmony of three critical elements: high-grade 6063 T5 aluminum profiles, precision PMMA linear lenses, and matching plastic end caps. By providing this integrated hardware ecosystem, we ensure absolute assembly precision and consistent optical performance.

In this new product release, we invite you to explore the ASEL Series—featuring the versatile AO20 and the boundary-breaking CMB.

ASEL AO20 Extrusion Lens Series

In the modern architectural landscape, the 20mm linear profile has emerged as the golden ratio for minimalist lighting. It is wide enough to deliver significant lumen output for functional tasks, yet slim enough to disappear into the clean lines of a contemporary ceiling or shelving unit. The ASEL AO20 Series was engineered to occupy this critical space, serving as a versatile, high-performance workhorse for designers who refuse to compromise between optical control and aesthetic purity.

The Mastery of Asymmetric and Multi-Angle Distribution

What truly separates the AO20 Series from generic linear diffusers is its sophisticated optical library. While traditional extrusion lenses often settle for a single, blurry flood distribution, the AO20 offers a surgical range of angles—from tight ~40x120° beams to ultra-wide ~150x100° floods.

The standout performer is the Asy35° (Asymmetric 35 degree) distribution. In commercial environments, light is often wasted on the floor or the tops of heads. The Asy35° lens solves this by tilting the intensity of the beam toward the vertical plane. When installed near a wall or above a retail display, it provides a flawless wash of light that highlights products or architectural textures without spilling wasted energy into the center of the room. This precision ensures that the AO20 isn't just illuminating a space; it is sculpting it. For general office lighting, the wider ~90x100° and ~150x100° options provide soft, uniform ambient light that minimizes shadows on workstations.

Material Integrity: Engineered for the 24/7 Environment

In high-traffic office and retail settings, lighting is a 24/7 commitment. To ensure the AO20 remains a permanent fixture rather than a maintenance liability, we utilize a premium 6063 T5 Aluminum profile. This specific grade of aluminum is prized for its exceptional structural rigidity and superior thermal conductivity. By acting as a highly efficient heat sink for 2835, 3030, or 3535 LED packages, the housing prevents thermal degradation, extending LED life and maintaining consistent color temperature.

Complementing this robust housing is the optical-grade PMMA lens. While inferior plastics may yellow or become brittle, our PMMA lenses maintain a transmittance of >90% for years, ensuring that energy reaches the target surface and maximizing efficiency.

Seamless Aesthetic and Installation Flexibility

A great lighting fixture should be seen through its effect, not its hardware. The AO20 Series features precision-engineered plastic endcaps that snap into place with a seamless fit, eliminating light leaks. To match the interior designer's vision, Asahi offers customizable anodized finishes—matte black, clean white, or custom colors.

Furthermore, the AO20 supports multiple mounting philosophies. For retail environments with frequently changing shelf layouts, magnet strip mounting allows for instant, tool-free repositioning. For permanent installations, surface-mounted brackets provide a rock-solid connection. This flexibility makes the AO20 ideal for everything from long-run office corridors and library stacks to intricate jewelry display cases.

ASEL CMB Extrusion Lens Series

While many linear systems are designed to simply flood a space with light, the CMB Series was born to address the most demanding challenge in linear optics: achieving the punch and focus of a spotlight within the streamlined form factor of an extrusion profile. In high-end retail and gallery design, the ability to pinpoint a specific object while maintaining the aesthetic of a continuous linear run is the ultimate holy grail.

The 10° Breakthrough: Defying the Limits of Extrusion

The most striking achievement of the CMB Series is the availability of an extremely narrow 10° beam angle. Achieving this within a continuous extrusion process is a feat of significant technical defiance.

Traditionally, achieving a tight, collimated 10° beam requires deep, bulky injection-molded TIR lenses. Extrusion lenses historically struggled with optical spill and fuzzy beam edges. Asahi Optics has shattered this limitation. The CMB Series delivers a clean light spot with sharply defined edges, ensuring light goes exactly where intended—on the merchandise—and nowhere else. This makes the CMB the first linear extrusion solution capable of true accent lighting, allowing designers to highlight textures and products with the intensity of a dedicated spot, all within a slim 17mm or 20mm profile.

±45° Rotational Precision: Light That Follows the Vision

In retail and exhibition spaces, change is constant. A static lighting fixture becomes a liability when it cannot adapt. This is why the CMB Series isn't just a lens; it is a dynamic structural system.

The matching aluminum profile supports a ±45° angle adjustment, allowing the entire optical unit to rotate. Whether you need to highlight a tall vertical display or tilt light into a deep shelf, the CMB adjusts in seconds, eliminating expensive re-wiring or relocation. When paired with magnetic or surface-mounted brackets, the CMB becomes an incredibly agile tool for wall-washing, task lighting, or intricate shelf illumination.

Miniaturization Without Compromise

Space is premium in modern commercial design. The CMB Series offers ultra-slim widths—17mm and 20mm—allowing it to be tucked into tight architectural niches or integrated into furniture without becoming a visual distraction. Despite this miniaturization, it maintains full compatibility with high-power 2835, 3030, and 3535 LED packages.

By utilizing the same 6063 T5 Aluminum and high-transmittance PMMA materials (>90%) as its AO20 sibling, the CMB ensures that even at its narrowest angles, the light remains vibrant and true to the source.

Application: From Boutiques to Corridors

The CMB Series thrives where good enough isn't enough:

• High-End Retail: Using 10° or 20° angles to create drama and contrast on luxury goods.

• Museums and Galleries: Utilizing rotational adjustment to highlight artifacts with precise beam control.

• Precision Wall-Washing: Creating sharp, grazing effects on textured surfaces in hotel lobbies.

By providing the profile, lens, and plastic endcaps as a unified kit, Asahi Optics guarantees that the sharp edges and clean spots promised on the spec sheet are exactly what you see on site.

Conclusion: Elevating the Standards of Linear Illumination

The ASEL AO20 and CMB series represent a significant leap forward in the fusion of architectural aesthetics and optical engineering. By moving beyond the limitations of segmented injection molding and embracing the seamless, continuous potential of precision extrusion, Asahi Optics has provided a solution that satisfies both the eye of the designer and the requirements of the engineer.

Whether you seek to illuminate a corporate corridor with the flawless asymmetric wash of the AO20, or highlight luxury merchandise with the sharp, rotating 10° precision of the CMB, these series deliver more than brightness. They deliver visual order. With full-system delivery including profile, lens, and endcaps, Asahi Optics ensures your vision remains unbroken, from the first millimeter to the last.

The future of linear lighting is no longer just a soft, blurry line; it is a sharp, controlled, and continuous expression of design.
