UV CaF2 Ø36mm

UV CaF2 Ø36mm

產品名稱 : UV CaF2 Ø36mm
產品說明 :
● Output Coupler (intra-cavity) for 248nm excimer lasers
● Calcium Fluoride substrates

Lasers that output wavelengths 193nm, 248nm, and 308nm are excimer lasers. These wavelengths are found in applications such as micro-lithography, micro-manufacturing, and medical devices. At these wavelengths, it is recommended to use Calcium Fluoride substrates for intra-cavity transmissive optical elements. Output coupler reflectance may be specified by the user.
