Rod integrator lens

Rod integrator lens

Rod integrator lenses are used to utilize the end face as the light entrance and exit surface, with the purpose of homogenizing uneven energy distribution.

Rod integrator lenses are used to utilize the end face as the light entrance and exit surface, with the purpose of homogenizing uneven energy distribution. The light incident on the rod integrator undergoes total internal reflection repeatedly, resulting in a uniform illumination distribution. By transferring the image of this exit surface with a relay lens, a uniform energy distribution can be obtained at the final surface.

Fly-eye lens

Fly-eye lens

For the uniform illumination of light sources. High-quality fly-eye lenses from Daiko Seisakusho.

The fly-eye lens (integrator lens), which structures lenses arranged vertically and horizontally to homogenize light, is widely used in semiconductor manufacturing equipment, industrial inspection devices, and projectors. By using a fly-eye lens, even light sources with strong diffusion can be converted into uniform light. Daiko Seisakusho's fly-eye lens enables the integration of quartz glass through its unique lens fusion processing technology (patent obtained), achieving high precision bonding with high strength, durability, and heat resistance.

Silica Lens for UV-LED, DLL Series

Silica Lens for UV-LED, DLL Series

This is a lens for LED packages designed to improve the efficiency and performance of UV-LEDs (especially in the deep ultraviolet range).

The UV-LED Lens DLL series is a self-designed lens with excellent light transmission and heat resistance. It exhibits particularly high effectiveness against deep ultraviolet LEDs. *We also offer cavity types that can accommodate LED elements. 【Features】 ◆ Excellent optical characteristics - Transmits light well across a wide wavelength range from IR to visible light to UV - Especially in the UV range, it has superior light transmission compared to other materials ◆ Excellent heat resistance - Capable of complex shapes that are difficult to achieve with quartz glass and similar materials - No deformation due to heat generated by chips compared to other materials ◆ Support from prototyping to mass production - Accommodates from a few pieces to mass production levels - Low cost through molding - Customizable through in-house optical design

TIR lens (deep ultraviolet compatible)

TIR lens (deep ultraviolet compatible)

The light from the LED is emitted widely, but it is focused by the TIR lens to create collimated light.

Our company utilizes glass molding technology with silica glass, creating highly directional light by passing light emitted from UV-LEDs at wavelengths below 400nm through TIR lenses. We also achieve high radiant intensity, especially with deep ultraviolet LEDs that emit light below 300nm, making our products suitable for various applications. 【Features】 - Excellent light transmission in UV light (especially in the deep ultraviolet range) - Outstanding heat resistance - Increased illuminance due to high directivity 【Customer Challenges】 - Deep ultraviolet LEDs are expensive, so we want to minimize the number of LEDs used while maintaining illuminance... - I want to focus the light from deep ultraviolet LEDs, but are there lenses compatible with the deep ultraviolet range (UVC)? - Concerns about whether sufficient illuminance can be achieved when the distance to the target object is large.
