Technical Info

The applications for optical thin film filters are so diversified that filter characteristics may be very much dependant on considerations such as the kind and intensity of light source, detector characteristics, and optical path geometry. We would be pleased to assist you in selecting a suitable standard filter or in establishing the specifications of your custom-made filter. Our production team is specialised in the manufacture of interference filters and dedicated to finding creative solutions for the filter problems in today’s high performance optical systems. Technical information gained through years of production experience and engineering developed in this specialised field, enable us to offer very high quality filters and complete technical assistance.

NOC filters can operate at temperatures of -20oC to 80oC without producing degradation of the filter characteristics. An extremely small wavelength shift (approximately 0.2nm / oC) is experienced with changing temperature. In addition, special manufacturing techniques are used for filters for applications at cryogenic temperatures.
