87-030 12.5 mm Dia. Dichroic Longpass Filter; t=1.05mm 1100nm
The 87-030 is a Dichroic Longpass Filter, boasting a 12.5 mm diameter and a thickness of 1.05mm, sourced from the renowned optical vendor, Edmund Optics. This filter is designed to transmit light with wavelengths above a specified cut-on value while reflecting or absorbing shorter wavelengths. In this case, the cut-on wavelength is 1100nm.
The filter's Dichroic coating, denoted as 'edm 87-030' on both the front and back surfaces, is a crucial component contributing to its functionality. This coating is designed to reflect specific wavelengths of light, thereby allowing the filter to perform its longpass filtering role effectively.
The filter's geometry, with a diameter of 12.5mm and a thickness of 1.05mm, is another significant aspect. The diameter is a critical factor in determining the filter's field of view, while the thickness can influence the filter's optical performance, particularly in terms of chromatic aberration and light scattering.
