Once in a Hundred Years of Astronomical Wonders--The Shooting of Jinxing Lingri
June 6th, 2012 is the last chance to observe the transit of Venus in this century. I took it and filmed it without regret. Shooting using our company: ND1000+ H-alpha and second generation sun filter. The shooting process is also very simple, full manual, 1 / 125 seconds, 200 sensitization, delay 2 seconds, the rest of the parameters are omitted.

A dielectric mirror, also known as a Bragg mirror, is a type of mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of glass or some other optical material.Their coating is more durable making them easier to clean and more resistant to laser damage.Broad Band supplying from 350~400 nm, 400-750nm, 750-1100nm, 1280-1600nm
We offer dielectric laser mirrors for fixed, narrowband or broadband wavelength applications covering wavelength ranges from UV to IR.
Changchun Ruiqi has a wide selection of spherical concave mirrors with metallic or dielectric coatings that together span the 250 nm - 1000nm spectral range, with focal lengths from 9.5 mm to 500 mm. Our mirrors with metallic coatings are offered in UV enhanced aluminum (250 - 450 nm), protected aluminum (450 nm - 700nm), protected silver (380 nm - 700nm), protected gold (400 nm - 700 nm), Our mirrors with dielectric coatings offer >99% average reflectivity in the 350 - 400 nm, 400 - 750 nm, 750 - 1100 nm spectral ranges.
