Product Details
Product Model: 61-6930-19
Product Brand: SIGMAKOKI CO., LTD.
Features
- Single crystals of germanium ***d in semiconductors have an infrared wavelength of 2~20 μm and low absorption, so they can be ***d as optical elements for infrared light.
- It is a window plate made of this germanium crystal.
- Wavelengths below 1.5 μm are not transmitted, so it can also be ***d as an infrared light transmission filter.
- It can also be ***d as a germanium substrate for various experiments.
- We also have a ZnSe window plate for infrared that transmits a portion of visible light.
- * The germanium window plate has a metallic luster, and visible light is not reflected or absorbed and transmitted.
- * The germanium window plate has a loss due to surface reflection (35% per surface [measured value]), so the transmittance is about 42%.
