Profile: Cheshire Optical, Inc. is a manufacturer and supplier of optical filters. We provide optical interference filters, optical bandpass filters, narrowband filters, hot mirrors, color process filters, UV filters, short-pass filters, long-pass filters, heat control filters and neutral density filters. Our long-wave pass and short wave-pass filters can be combined in pairs to create transmission bands, allowing for independent control of the cut-on & cut-off wavelengths. Our heat control filters direct the desired portion of an illumination spectrum through an optical system, while diverting the unnecessary and potentially detrimental portion of the source energy.
