COE Optics offers high-quality UV & IR grade sapphire windows with low scattering and birefringence, ideal for harsh environments. These defect-free windows, made from synthetic corundum, achieve T >70%@190nm and T >85%@4.3μm. Used in watches, electro-optics, aerospace, biomedical fields, LEDs, and barcode scanners, they are highly durable and reliable.

IPL light guides and filters are crucial for IPL machines, filtering UV waves and preserving wavelengths from 400nm to 1200nm for cosmetic lasers like photorejuvenation and hair removal. Available wavelengths include 400 to 810nm. IPL devices use high-output flash lamps to produce broad wavelength light. Dichroic filters target specific wavelengths, enhancing versatility. Large spot sizes enable swift treatment of large areas.

COE Optics’ lenses, made from annealed BK7 glass, sapphire, optical glass, silicon, and germanium, meet laser electro-optic demands. They focus or disperse light via refraction and are available as biconvex, biconcave, Plano-convex, Plano-concave, or meniscus lenses. Positive lenses converge light, while negative lenses diverge it.

COE Optics offers a wide range of optical prisms designed for various applications. These prisms redirect light to a specific angle and are available in different designs, substrates, and coatings. Types include right-angle prisms, corner cube retroreflectors, penta prisms, and rhomboid prisms, each serving unique optical purposes​

Designed for use in various laser and imaging systems, COE Optics’ rod lenses are polished on the circumference and ground on both ends, similar to a cylinder lens. They focus collimated light into a line and are available in diameters as small as 1mm. N-BK7 and UV fused silica substrates support UV, visible, and NIR applications. Ideal for rigid endoscopes, these lenses reduce vignetting and simplify assembly.

A long pass (LP) filter is an optical interference or colored glass filter that attenuates shorter wavelengths and transmits longer wavelengths. It is characterized by a sharp slope at the cut-on wavelength at 50 percent peak transmission. In fluorescence microscopy, these filters are used in dichroic mirrors and barrier filters. The term ‘low pass’ for LP filters is now rare.
