Specifications
| Material | Glass |
|---|---|
| Type | Color Filter |
| Shape | Customized |
| Usage | Lighting, Medical, Optical |
| Model NO. | AT-61047 |
| Thickness Range | 5mm-10mm |
| Color | Purple |
| Principle | Selective Absorption Filter |
| Angle of incidence | 45° |
| Light Transmission Properties | Typically covers the purple light wavelength range (380-450 nm), with possible slight extensions into adjacent blue or ultraviolet regions (specific ranges vary by model). |
| Absorptive Filters | These filters absorb light of other wavelengths using dyes or glass, offering lower costs but potentially generating heat. |
| Interference Filters | Based on the principle of thin-film interference, these filters provide high precision and stable performance, often used in precision instruments. |
| Material Options | Optical glass (heat-resistant), resin (lightweight and easy to process), quartz (suitable for ultraviolet light), etc. |
| Main Applications | Photography and Videography |
| Supplier | Shanghai Anttrans Technology Co., Ltd |

What to specify when you request a quote
- Spectral target — state the centre or edge wavelength, the bandwidth and the minimum transmission in the passband.
- Blocking — give the blocking range and optical density (OD) the system needs.
- Angle of incidence — listed as “45°”; interference filters shift with angle, so specify the operating angle and cone.
- Size and thickness — listed as “5mm-10mm”; give outline, thickness and tolerance, and whether the filter is mounted.
- Substrate — listed as “Glass”; name the substrate glass if thermal or UV behaviour matters.
- Surface quality — quote scratch-dig for imaging paths.
