General Optics designs optical filter coatings for precise spectral control. These include neutral density (ND) filters for attenuation, bandpass filters for wavelength selection, and dichroic/edge filters for spectral separation. Every filter is custom-designed to order, covering applications from UV through IR.
Key Features:
- ND filters: controlled attenuation with optical density (OD) specification
- Bandpass filters: narrow or wide transmission windows
- Dichroic/Edge filters: long-pass and short-pass designs
- Durable, high-power laser compatible coatings
- Spectral coverage from UV to IR
Applications
- Laser power control (ND filters)
- Spectroscopy and fluorescence detection (bandpass)
- Multi-source optical systems (dichroic/edge filters)
- Medical, research, and defense applications
