745 NOTCH 72 mm Dia. Surface Coating; Notch (Rejection Band) Filter Surface Coating
The 745 NOTCH filter, with a 72 mm diameter, is a notch filter developed by Omega Optical. This filter is designed to reject a narrow band of wavelengths while transmitting wavelengths on either side of the notch. The specific notch for this filter is centered at 745 nanometers, making it ideal for applications that require the rejection of this wavelength.
The filter is made from UVFS MAL-1965 material, a type of optical glass known for its excellent transmission properties and durability. The filter has a thickness of 1.5 millimeters, providing sufficient structural integrity while minimizing optical distortion.
The front and back surfaces of the filter are coated with the OME 745 NOTCH coating. This coating is specifically designed to enhance the filter's performance, ensuring a high level of rejection for the specified wavelength. The coating also provides excellent environmental stability, ensuring the filter maintains its performance characteristics over time.
The filter is shaped as a thin lens, which is beneficial for applications that require a compact, lightweight optical component. This shape also allows for easy integration with other optical elements in a system.
