This is a 15 x 25 mm White Float Rectangular Window, with a thickness of 1 mm, sourced from Knight Optical. The window is made of soda lime ru clear material, which is a common choice for optical elements due to its excellent clarity and durability.
The window is of the Flat Window sub-type, which means it does not have any curvature. It is rectangular in base shape, making it suitable for applications that require a flat, rectangular window. The geometry of the window is defined by its width (15 mm), length (25 mm), and thickness (1 mm).
The window is designed to work with a wavelength of 633 nm, which is typically used in various applications such as laser systems and spectroscopy. The window's shape is thin lens, which suggests that it can be used in systems where light needs to be focused or collimated.
Notably, this window does not have any coating, which means it is uncoated. This could be beneficial in applications where coating might interfere with the desired optical properties. However, it's important to consider that uncoated windows may have higher surface reflectivity, which could lead to light loss in some applications.
The window is currently in stock and available for purchase on Knight Optical's website.
