34-496 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 422nm
The 34-496 is a 12.5 mm diameter Bandpass Filter, supplied by Edmund Optics, with a center wavelength of 422nm and a 10nm bandwidth. This filter is designed to transmit light within a specific range of wavelengths while blocking other wavelengths, making it ideal for applications requiring narrow-band spectral filtering.
The filter is hard coated on both sides with the front coating designated as 'edm 34-496' and the back coating as 'edm 34-496'. This coating enhances the filter's durability and resistance to environmental factors, ensuring reliable performance over time.
The filter's geometry includes a diameter of 12.5mm and a thickness of 3.5mm. The cut-on wavelength is 417nm, and the cut-off wavelength is 427nm, providing a narrow passband around the central wavelength. This makes the filter suitable for applications requiring high spectral selectivity.
The filter is designed in the shape of a thin lens, which can be beneficial in certain optical systems where minimal thickness and weight are desirable. The catalog number for this filter is 34-496, and it is currently in stock, according to the vendor's website.
