First Surface Mirror
Optical grade first surface mirror designed for science and engineering.
Precision cutting, fast shipping, and outstanding quality at your fingertips.
Discover The Mirror
A first surface mirror, also known as a front surface mirror, is an optical mirror which provides superior accuracy for engineering and scientific applications. Unlike a standard mirror, which has the coating on the back side, a first surface mirror provides a true reflection with no double image.
First surface mirrors have an aluminum mirror coating on the face of the glass that maximizes the amount of light reflected, minimizes distortion, and prevents a double image, also known as “ghosting.”
The enhanced aluminum mirror coating is optimized for the visible spectrum. A dielectric overcoat prevents scratching and oxidation. Strict standards and carefully selected glass ensure industry leading quality.
1λ first surface mirrors provide optical quality at an affordable price.
λ/4 flatness mirrors offer a polished substrate for higher accuracy.
λ/8 is superior for equipment using a high magnification.
Chemically hardened first surface mirrors offer superior strength.
UV Enhanced FSM offers superior reflection for 10-400nm light.
Shatterproof & easy to cut. Hobby grade reflection for lighting effects.
Questions? We've Got Answers.
Do you ship outside of the United States?
Yes, we ship worldwide via FedEx and shipping is automatically calculated when you check out. Duties and taxes are billed separately on delivery.
Do you sell samples?
Yes, for your convenience we sell mirror samples (limit 1 per customer).
What's the largest size you can make?
The largest sizes we can make are: 72″x96″ for 1/4″ thickness glass and 49″x97″ for 1/8″ and 1/4″ acrylic
How do you prevent breakage in shipping?
We carefully package and fully insure all of our shipments. If it should arrive broken, please send us pictures of the box and broken glass and we will ship you a replacement.
Are the mirrors sharp?
We carefully sand the edges and corners with a wet belt sander to take off the sharp edge.
How should I clean them?
How accurate is your cutting?
We typically cut to +/- 1/16″ (1.5mm) unless added accuracy is requested.
Why use aluminum instead of silver or gold?
Aluminum provides the best reflection, durability, and quality for most applications. We receive a lot of requests for gold and silver first surface mirrors, and can manufacture them on request.
Silver coatings theoretically have good reflectance wavechart, but because silver is so reactive to the air and chemicals, often the real life results don’t measure up to the theoretical specification.
Gold coatings are non-reactive and have good reflectance across a large spectrum, but because gold is so soft it’s nearly impossible to clean the mirrors without damaging them. Gold coatings are also several times as expensive as aluminum, so they are generally cost-prohibitive for most applications.
