Optics & Coatings

6080 Paint   Crystal Optics   Optics

Pro-Lite's barium sulphate coatings are scientific-grade paints that exhibits near-perfect diffuse reflectance at levels up to 98% in the 250-2500nm (UV-VIS-NIR) wavelength range. Available as an affordable water-based formulation or as a fast-drying ethanol pre-mix or ethanol solution, barium sulphate is used to coat integrating spheres, lamp housings, backlight reflectors and laser pumping chambers, in fact anywhere where you need efficient, uniform illumination.

Pro-Lite supplies holographic, light-shaping diffusers from Luminit. Compared with traditional transmission diffuser material, a holographic diffuser provides for precise control of the shape of the transmitted beam, in addition to homogenising the light and providing for excellent hiding of the light source and reduction of undesirable hot-spots. Holograhpic diffusers are an enabling technology in many lighting, automotive and display applications.

Spectralon Laser Cavity Reflectors


Reflectance Material


Zenith Transmission Diffusers

Spectralon Laser Cavities   Spectralon  

Labsphere's Spectralon is used as a pumping chamber reflector in diode and lamp pumped solid state lasers and lamp pumped dye lasers. Spectralon exhibits diffuse, high reflectance leading to increased slope efficiencies, higher energies, increased gain uniformity, improved beam quality and reduced risk of parasitic oscillations. Spectralon is easily machined into bespoke reflectors.

Labsphere's Spectralon is a solid thermoplastic that exhibits the highest diffuse reflectance of any material or coating in the 250-2500nm band. Spectralon is used in integrating spheres, laser cavity pumping chambers, reflectance standards and targets, lamp reflectors, display backpanel lighting and digital imaging devices. Spectralon is easily machined into bespoke reflectors.

  Zenith diffusers are made of the same material as our reflectance standards with its unique, highly lambertian optical properties. Thin section Zenith sheets are used as cosine diffusers minimise angular dependency of the light reaching a photodetector or to create more even illumination from a light source.
