Product Model: 61-6948-44
Product Brand: SIGMAKOKI CO., LTD.
Features
- The frame of the mirror holder has been removed and the front of the holder has been completely mirrored.
- High precision polishing of ceramics with a low coefficient of thermal expansion on the substrate provides extremely high surface accuracy and temperature stability.
- We have a lineup that can be ***d for various wavelengths of YAG lasers.
- As for the mirror type, since the dielectric multilayer film is coated on high-precision polished ceramic, it is not so different from the dielectric multilayer film mirror coated on glass.
- The effective area of the mirror has been expanded to the limit, and a compact mirror adjustment mechanism has been realized.
- Since the reflected wavefront does not collapse due to temperature change, it is ideal for precise optical systems.
- This product guarantees surface accuracy after coating (holder condition).
- High laser capacity and can be ***d with high-power lasers.
- This product was patented by the company in November 2011.
- The mounting method to the base is the same as the MHG mirror holder.
- Can be attached to post stand PST -** (sold separately) and rod RO -** (sold separately).
- * Reflectance wavelength characteristics of dielectric multilayer films vary dep***ing on the polarization state of the incident beam.
- * P-polarized light has a lower reflectivity and a narrower reflection band than S-polarized light.
- * The reflectance of the specification is expressed as the average value of the reflectance of P-polarized light and S-polarized light.
- Reflectance may be low when ***d at angles other than 45°.
- Reflectivity may be low when the watch is ***d at wavelengths other than the adaptive wavelength.
- * Surface accuracy guarantee data is not attached to the product.
