Attention! You can customise this product to your needs.
Our standard substrates have laser grade polishing on both surfaces. These substrates are ideal for transmission applications such as beamsplitters, windows, partially reflecting mirrors etc.
Laser components require highly polished substrates as well as high performance coatings. Scattering, damage by laser light can occur if the substrate is made of inferior material or is inadequately polished. For UV and very high power applications we recommend using UVFS substrates. BK7 substrates are an economical solution for laser components used in many laboratory applications as well as in many devices and instruments.
Under customer request dielectric or metallic coatings can applied.
varna Ideal for transmitting applications such as beamsplitters, windows, partial reflecting mirrors etc.
varna UVFS substrates are recommended for the UV and very high energy applications
varna Windows up to 500mm diameter are available
