Windows are used to isolate different physical environments while allowing light to pass. The selection of a window should consider the properties of the different optical materials, transmission, wavelength range, and resistance to the environment. Tower offers a wide range of different materials and a variety of anti-reflecting coatings that can be deposited on the windows.
Tower Optical manufactures windows from BK7, UV Grade Fused Silica and Sapphire. Other materials are available on a custom basis. In addition, we offer three different quality standards as described below. Contact factory for info on Sapphire Windows.
Mirrors are smooth, and contain a highly polished surface for reflecting light. The reflecting surface is usually a thin coating of aluminum or silver. Most mirrors for optical applications are called front surface types since the coating is on the front surface thereby eliminating the optical properties of the glass from affecting the incident or reflected light. The rear surface is usually fine ground. All of the following mirrors have a protected Aluminum coating applied to the front surface.
