OPCFU-40C04-P 40 mm Dia. CaF2 Round Flat Window; t=4 mm Uncoated

The OPCFU-40C04-P is a 40 mm diameter Calcium Fluoride (CaF2) flat window, offered by OptoSigma. This window, with a thickness of 4 mm, is uncoated and designed for use in ultraviolet and infrared laser applications.

The window is circular in shape, a common design for optical components as it provides uniformity and consistency. The flat design ensures that the window does not distort the incoming light, making it ideal for applications where minimal optical aberration is required.

The CaF2 material is known for its excellent transmission properties in the ultraviolet and infrared regions of the spectrum. This makes the OPCFU-40C04-P suitable for a wide range of laser applications, including UV curing, spectroscopy, and medical lasers.

The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where a specific coating may interfere with the laser's performance. However, it's important to note that uncoated windows may be more susceptible to environmental factors such as dust and moisture.
