NC-W-38.5x19.5x4 38.5 x 19.5 mm NaCl Flat Window; t=4mm Uncoated

This is a flat window optical element sourced from Alkor Technologies, a renowned vendor in the optical industry. The item, identified as NC-W-38.5x19.5x4, is a rectangular flat window with a base shape that is 38.5 mm in width and 19.5 mm in height. The thickness of the window is 4 mm, providing substantial structural integrity while maintaining a slim profile.

The material of this flat window is uncoated sodium chloride, also known as NaCl, which is identified in the item data as "uvfs mal- 1965". This material is widely used in optical applications due to its transparency and chemical stability. The window is designed to transmit light at a wavelength of 633 nanometers, making it suitable for a wide range of applications.

The window's shape is that of a thin lens, which suggests that it can be used in applications where light needs to be focused or collimated. However, the item data does not provide information about any coatings on the window. Therefore, it can be assumed that the window is uncoated, which may affect its light transmission properties and susceptibility to environmental factors.
