The Cf-pc-12.7-50 is a plano-concave lens with a diameter of 12.7 mm, sourced from Alkor Technologies. This lens is made of Calcium Fluoride (CaF2) material, specifically the Mal-1963 variant, which is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum.
The lens features a concave shape with an inner radius of 0 mm and an outer radius of 0 mm. The center thickness of the lens is 1.5 mm. The effective focal length (EFL) of this lens is -50.8 mm, indicating that it is a diverging lens, which spreads out light rays that pass through it.
This lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can make the lens more susceptible to environmental factors such as dust, moisture, and scratches, but it also means that the lens does not introduce any additional chromatic aberration or other optical distortions.
The lens is designed to work with a wavelength of 5000 nm. It is important to note that the performance of the lens can vary depending on the wavelength of the light it is used with. Therefore, it is crucial to ensure that this lens is suitable for your specific application before purchasing.
