660DF40-24.3MM 24.3 mm Dia. Surface Coating; Bandpass Filter Surface Coating
The 660DF40-24.3MM is a Bandpass Filter, a type of optical filter that allows only a specific range of wavelengths to pass through while blocking others. This particular filter, sourced from Omega Optical, has a center wavelength (CWL) of 660 nm, making it ideal for applications that require precise filtering around this wavelength.
The filter is circular in shape with a diameter of 24.3 mm and a thickness of 3 mm, providing a robust and compact design. It is made from UVFS MAL-1965, a material known for its optical properties and durability.
The 660DF40-24.3MM features surface coatings on both the front and back, specifically the OME 660DF40-24-3mm coating. This coating enhances the filter's performance by ensuring optimal transmission and blocking of unwanted wavelengths.
The physical data of the filter includes a cut-on wavelength of 640 nm and a cut-off wavelength of 680 nm. This means that the filter starts transmitting at 640 nm and stops transmitting at 680 nm, effectively passing wavelengths within this range.
