NC-W-50.8-5 50.8 mm Dia. NaCl Flat Window; t=5mm Uncoated

The NC-W-50.8-5 is a 50.8 mm diameter Flat Window, sourced from Alkor Technologies, a renowned vendor in the optical industry. This window is designed with a circular base shape and a uniform thickness of 5mm, making it an ideal choice for applications requiring consistent optical path length and minimal distortion.

The window is made of NaCl, or Sodium Chloride, a material with a refractive index of approximately 1.5, similar to that of common glass. This makes it a suitable alternative in applications where glass may not be ideal due to its susceptibility to thermal shock or where a lower refractive index is desired.

The window is uncoated, meaning it does not have any additional layers of material applied to its surface. This can be beneficial in applications where maintaining the natural properties of the NaCl material is crucial, or where cost-effectiveness is a significant factor. However, it's important to note that uncoated surfaces can be more susceptible to environmental factors such as dust, moisture, or scratching, which may affect the window's performance over time.

This window is designed to work with a wavelength of 633nm, making it suitable for a wide range of applications in the visible light spectrum. Its thin lens shape ensures minimal optical aberrations, providing clear and accurate optical transmission.
