Color temperature correction filters are designed to correct the color temperature of projected light. This can be achieved with a flat filter placed in front of the light source (managing what wavelengths are transmitted) or with a filter deposited on the surface of a reflector (managing what wavelengths are reflected). Typical applications for color temperature correction filters include: displays; photographic; theatrical; and medical. The design of a color correction filter depends on the light source being corrected. Color correction filters/reflectors are customized to achieve the desired performance. Dynasil provides color temperature correction filters through EMF. Please contact EMF directly to discuss your color temperature correction filter needs.
Optical filters are used in a broad range of applications such as clinical chemistry, fluorescence microscopy, machine vision inspection, and spectroscopy. Dynasil’s EMF and Optometrics produce a broad range of optical filters that are used to selectively transmit or reflect a specific wavelength or range of wavelengths.
DichroFilm™ color filters are used to transmit colors of well defined spectral characteristics for applications like display and theatrical lighting. Unlike gels and polymers that absorb unwanted wavelengths, DichroFilm™ filters reflect the unwanted wavelengths while transmitting the desired wavelength color, producing a specific color more efficiently than gels or colored glass. Dynasil manufactures DichroFilmTM filters through EMF. Please contact EMF directly to discuss your DichroFilm™ filter needs.
Edge filters are a range of filters that can reject bands of wavelengths. A long pass or long wave pass filter (“LP”) is one that transmits at longer wavelengths and rejects shorter wavelengths. A short pass or short wave pass filter (“SP”) is a filter that transmits at shorter wavelengths and rejects longer wavelengths. SP and LP filters are useful in applications where spectral noise reduction is important or for isolating a particular region of the spectrum. They can be used as emission filters in fluorescence applications, in spectroscopy, as order sorting filters, and in astronomical applications. Dynasil provides edge filters through Optometrics. Please contact Optometrics directly to discuss your edge filter needs.
