Ootee Optics fabricate many kinds of optical filters including color glass filter, neutural density filter, band pass filter, IR cut filter, IR pass filter, Edge Filters, interference filter, etc..
Bandpass Filters
Bandpass filters are basically designed to selectively transmit a particular spectrum range and reject the other wavelengths. Bandpass filters are commonly used in a variety of applications, including chemistry, fluorescence microscopy, high-speed optical imaging, and spectroscopy.
Neutral Density（ND） Filters
Neutral density filters can be used to reduce the intensity of light by reflecting or absorbing a percentage of light at a specific wavelength. Neutral density (ND) filters reduce light intensity by absorbing or reflecting light and provide even attenuation across all visible wavelengths.
Dichroic Filters
Ootee Optics fabricates dichroic filters to transmit a particular range of the spectrum (the passband) while reflecting another range (known as the rejection band). Dichroic filters are commonly used for color separation in digital projection and CCD imaging. we can handle the custom fabrication of even the most complex dichroic filters.
Edge Filters
As with other kinds of optical filters, edge filters are designed to separate a broad spectrum of light into light that is transmitted, and light that rejected, or blocked. Edge filters can be used to reduce harmonics and light scatter and can be fabricated to function as longpass, shortpass, or bandpass filters.
Color Filters
Color glass filters are fabricated to selectively transmit a particular range of wavelengths or colors of light. In designing color filters to transmit a particular range, they’re also designed to block other wavelengths (or colors). we can fabricate custom color filters to allow long wavelengths to pass (longpass), or shortwave lengths (shortpass), or both (bandpass).
Infrared (IR) Filters
Infrared filters allow for high transmission in the IR spectrum and strong rejection to isolate even the narrowest band of wavelengths. As their name implies, IR filters can be fabricated for use in the harshest environments in FLIR, security, environmental and other infrared applications.
