カスタム可能なスペック
Hereunder are several “standard” filters, if you need another specific Transmission profile, please contact us.
Each delivered filter will be accompanied by its spectral curve at normal incidence and room temperature.
Spectrogon’s filters and windows are produced in sizes from Ø6.0 to Ø200.0 mm. Custom sizing service is available at a modest surcharge. The wafers can be diced to custom-made sizes, down to as small as 1.0×1.0 mm. To minimize handling and cost, Spectrogon can offer – on most filters and windows – cutting and delivering on tape. Also turning down to smaller diameter is possible.
Spectrogon can provide non-standard spectral measurements with its filters with extra cost:
- other than normal incidence angle
- Reflectance
- at up to 500 K (227 °C)
- at 77 K (-196 °C)
- at 7 K (-266 °C)
