34-495 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 413nm

The 34-495 is a Bandpass Filter, sourced from Edmund Optics, with a diameter of 50 mm and a thickness of 3.5 mm. This filter is designed to transmit light within a specific range of wavelengths, while blocking other wavelengths, making it ideal for applications requiring wavelength selectivity.

The filter's central wavelength (CWL) is 413nm, which is the wavelength at which the filter has its maximum transmittance. The cut-on wavelength is 408nm, and the cut-off wavelength is 418nm. This means that the filter starts transmitting at 408nm and stops transmitting at 418nm, effectively passing light in the 408-418nm range.

The 34-495 features hard coating on both the front and back surfaces, denoted as 'edm 34-493'. This coating enhances the filter's durability and resistance to environmental factors, ensuring longevity and maintaining performance over time.

The filter's geometry is defined by its circular shape and thin lens design. The circular shape is a common choice for optical components due to its ease of integration into various systems. The thin lens design reduces the filter's weight and potential optical aberrations, contributing to improved system performance.
