T-G10-120-B - Ø1" N-BK7 Ground Glass Diffuser, 120 Grit, ARC: 650-1050 nm
T-G10-120-B - Ø1" N-BK7 Ground Glass Diffuser, 120 Grit, ARC: 650-1050 nm
Features
- Ø1", Unmounted Circular Diffusers
- One of Two AR Coatings on Both Surfaces:
- 350 - 700 nm (A Coating)
- 650 - 1050 nm (B Coating)
- Substrate Material: N-BK7
The coated diffusers offer increased transmission over their uncoated counterparts, which are represented by the blue curves in the graphs below.
The blue-shaded region represents the wavelength range over which the AR coating is specified. The -A coating is specified for 350 - 700 nm and the -B coating for 650 - 1050 nm.
Please note that the transmission values are affected by the manner in which the data is collected. An integrating sphere is used along with a spectrometer, and as the grit values get smaller the light is more dispersed, making it difficult to collect all of the light into the spectrometer. Therefore, lower grit values will appear to have a lower transmission.
