Description
Circular, Square, Rectangular Mirrors from Tower Optical are crafted with precision to meet the highest standards of optical performance. These mirrors feature a highly polished surface designed for optimal light reflection, making them ideal for a variety of optical applications. The reflecting surface is typically a thin coating of aluminum or silver, applied to the front surface of the mirror. This first surface design ensures that the optical properties of the glass do not interfere with the incident or reflected light, providing superior clarity and accuracy.
Each mirror is coated with a protected aluminum layer on the front surface, ensuring durability and longevity. The rear surface is finely ground to maintain the integrity of the mirror's structure. The mirrors are available in both standard and high-grade options, with materials such as BK7 grade A optical glass and UV grade fused silica. These materials are chosen for their excellent optical properties and reliability in demanding environments.
At Tower Optical, quality is paramount, and we believe it is priceless. Our mirrors are manufactured to precise specifications, with tight dimensional tolerances and exceptional surface quality. Whether you require a standard size or a custom solution, we are committed to providing mirrors that meet your exact needs. For custom versions, simply send us your drawings or specifications, and we will be happy to provide a quotation.

Frequently Asked Questions
The purpose of a circular mirror is to reflect light.
The reflecting surface of the mirror is usually a thin coating of aluminum or silver.
A first surface mirror is a mirror where the coating is on the front surface, eliminating the optical properties of the glass from affecting the incident or reflected light.
The difference between standard grade and high grade material is that high grade material can be either BK7 grade A or fused silica, while standard grade material is only BK7 grade A.
The thickness tolerance of the mirrors is ±0.2 mm.
