Mirror Laser Mirror: Laser mirror is characterized by a dielectric coating optimized to have a high reflectance at a specific laser wavelength. These mirrors typically receive a damage threshold test and are used in the most popular laser wavelength. *Excimer Laser Mirror *ND;YAG Laser Mirror *CO2 Laser Mirror Metal Mirror: As a metal coating mirror including Al, Au, Ag, Cu, Cr, etc., reflectivity and uniformity of the broad wavelength are excellent.

Mirror Dielectric mirror : Dielectric Mirror is suitable for laser or highly reflective applications. These mirrors are designed to have a maximum reflection at the measurement wavelength or the band. Large Size Mirror We guarantee of the highest quality. % R> 99.5% of High Power Excimer & Yag Laser Mirror -Max size 2000mmx1500mm Astronomical telescope Aspherical Mirror We guarantee the best quality in core aspherical mirror, process of lens, aspherical, coating, measurement for astronomical, satellite use. -Max size φ1500mm -Material Zerodur, Ceramic, Fused Silica

Filter Scope of products Band Pass Filter : Only selected wavelengths are transmitted and the rest is blocked. Shot/Long Pass Filter : manufactured to have a very sharp conversion from reflection to transmission, so it is useful in many applications. ND Filter :mainly used to typically reduce the light of the broad wavelength.

Prism Features 0.5 arc sec resolution measurements can assure the angle. Optical Bonding to withstand the High Power enables to manufacture the Cube. Optical Bonding is possible without absorbing to the UV Range. The confidence in measuring squareness and parallelism is assured by the latest measurement equipment. Various types of prisms and long size of precision prism are produced. The edge can be processed without chamfer.
