34-502 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 473nm

The 34-502 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for a central wavelength of 473 nm, making it ideal for applications that require narrowband transmission at this wavelength.

The filter is hard coated on both sides with the front coating designated as 'edm 34-502' and the back coating as 'edm 34-502'. This coating ensures durability and resistance to wear and tear, making it suitable for use in various environments.

The filter has a thickness of 3.5 mm and a clear aperture, providing a sufficient area for light transmission. The cut-on wavelength is 468 nm, and the cut-off wavelength is 478 nm, indicating a narrow bandwidth of 10 nm. This characteristic is crucial for applications that require high spectral selectivity.

The 34-502 filter is designed in a circular shape, a common form factor for optical components due to its ease of integration into various systems. It also features a Thin Lens shape, which implies that it has a very small thickness compared to its diameter, making it suitable for applications where space is a constraint.
