Product Model: 61-6873-39
Product Brand: SIGMAKOKI CO., LTD.
Features
- A mirror in which aluminum is deposited on a plane substrate that has been polished with high precision.
- High reflectivity can be obtained at all incident angles.
- A protective coating of dielectric multilayers designed to increase the reflectance of visible and ultraviolet light.
- The reflectivity is slightly reduced, but the reflectivity is stable even in visible and infrared light.
- Pyrex (R) is a registered trademark of Corning Corporation.
- * When multiple mirrors are ***d to propagate light, large amounts of light are lost due to absorption of the aluminum film.
- * Use a dielectric multilayer mirror (TFM, etc.).
- * The reflectance of the specification is expressed as the average value of the reflectance of P-polarized light and S-polarized light.
- * Reflectivity may change dep***ing on the polarization state of the incident beam.
