Front Surface Mirrors

Front surface mirrors, also called first surface mirrors, are among the most important components in the field of optics. Unlike traditional mirrors, whose coating lies at the back of the glass, front surface mirrors possess one or more reflective layers on the outside or front surface. This design offers several technical advantages that are essential in most optical applications. A primary benefit of front surface mirrors is their ability to eliminate what are commonly known as “ghost images” or multiple reflections. With conventional mirrors, the light is reflected from the back of the glass. Since it has to pass through the glass twice, secondary reflections are created from the first surface, which superimpose the image to be reflected. This secondary reflection can cause ghosting, where the viewer perceives not only the main image but also a fainter, undesirable duplicate reflection. Front surface mirrors, conversely, reflect from the outer surface only, eliminating any secondary reflections and producing clear images without distortions. Because of their superior and precise imaging quality, front surface mirrors are used for optical systems and laser applications. They provide significantly better flatness, surface quality, and reflectivity than ordinary backside-coated mirrors.

Below you will find links to the data sheets for the standard optical mirrors we manufacture, which can be ordered at almost any time:

 

 

SEA-VIS Enhanced Aluminum Front Surface Mirror (VIS)

Our SEA-VIS front surface mirrors consist of an Al layer with multilayer dielectric overcoatings. These overcoatings are used to enhance the reflectivity and protect the aluminum thin-film coating. We mainly designed the SEA–VIS for the visible wavelength range. It can also reflect up to medium-power laser beams. This first surface mirror is the best choice for volume applications because it offers excellent performance at a low cost. We can add and modify the layers to improve the reflectivity for other specific wavelengths. Depending on the thickness, we produce our SEA–VIS up to a size of approx. 800 mm × 1200 mm.

SEA-NIR Enhanced Aluminum Front Surface Mirror (NIR)

The SEA–NIR front surface mirrors are also aluminum-coated. They have a premium-quality glass substrate for the best imaging quality. Like the SEA–VIS, they feature an additional reflectivity-increasing overcoating. We optimized the overcoating layers of the SEA–NIR for enhanced near-infrared reflectivity. In some use cases, the SEA-NIR can even replace gold mirrors. Like the SEA-VIS, you can use the SEA-NIR as a laser front surface mirror for small to medium laser power. Show details...

 

SEA-UV Protected Aluminum Front Surface Mirror (UV-VIS-IR)

The SEA–UV front surface mirror series has an aluminum coating protected only by an ultra-thin protective quartz layer (SiO2), which is thin enough to maintain excellent UV reflectivity and thick enough to prevent the coating from oxidizing. The optics offer very broadband reflectivity up to the infrared wavelength range. We coat the SEA–UV on glass substrates with mirror quality. Show details......

 

SHP Silver-Metal Front Surface Mirror (VIS)

The SHP is a silver-metal-coated precision front surface mirror. It provides powerful reflectivity for polarized and unpolarized light. The mirror is based on premium-grade glass substrates and has a thin protective layer that prevents the silver coating from oxidizing. To the data sheet...

 

SHP-D Front Surface Mirror for Polarized Light (VIS)

We based our SHP-D front surface mirrors on high-reflection metal-free layers optimized for polarized and unpolarized light and lasers in the VIS range. More details...

 

SHR Dielectric Front Surface Mirror (VIS)

The SHR first surface mirrors feature enormous efficiency and low absorption in the VIS wavelength range. We apply the SHR layers to premium-grade borosilicate glass substrates. The SHR is also an economical laser mirror with very high reflectivity. More details...

 

SHD Cold Mirror (VIS)

Our SHD cold mirror is heat-permeable and offers strong reflectivity in the visible wavelength range. It can separate the IR from the VIS spectrum and provides excellent imaging quality. We deposit the SHD coating on selected borosilicate glass substrates, enabling the mirror to withstand high temperatures. More details...

 

DST Beamsplitter Plates | Partially Transmitting Mirror (VIS)

We designed the precision DST divider mirror for random polarization and optimized the partially transparent layer system of the optics for the VIS region. The divider mirror features an additional AR coating on the backside, has virtually no ghost imaging effects, and offers high image quality. More details!

 

SIR Heat-Reflecting Hot Mirror

Our SIR heat-reflecting hot mirror can be operated as an IR front surface mirror for wavelengths up to 1100 nm and is highly transparent in the visible. We deposit the SIR multilayer coatings on premium-quality borosilicate glass materials. Besides its primary use as a heat filter, it also works in eye-tracking systems and other medical applications. To the data sheet...

 

SIR-IR Hot Mirror with Extended Blocking Range

The SIR-IR works similarly to the SIR hot mirror but has an extended reflection range in the infrared spectrum, allowing broader heat radiation blocking. The IR reflection of the SIR-IR is less effective but has a higher bandwidth than our standard SIR. More details...

 

SUV Ultraviolet Cold Mirror

Our SUV-UV-cold mirror offers ultraviolet reflectivity as well as heat transmission. More details...

 

TDS-Spy Mirror – “One-Way-Mirror” – “Smart Mirror”

The TDS is a glass-based, partially transmitting first-surface spy mirror that only appears transparent from one side under the right lighting conditions. Show details...

 

Are you searching for a front surface mirror you can't find here?

Don't hesitate to request a quotation for your customized optical front surface mirror optics. We can customize each front surface mirror regarding cut-on or cut-off points on a batch basis. We can use other glass substrates and add or modify thin-film coating systems to create almost any custom mirror (dielectric, gold, chrome, or other metals) to your application's exacting requirements. Please click here for additional information about our manufacturing, help, and free support to find the best solution for your application.

Note: We do not coat mirror coatings on acrylic or plastic substrates, as they usually can't offer the imaging quality possible with glass. Moreover, acrylic does not withstand higher thermal loads. We generally only fabricate coated glass mirror optics. Moreover, we don't make conventional backside-coated mirror components for non-optical use. All the first surface mirror series listed on our website are in stock and available within our 48-hour express optics service, allowing shipping within two business days after receipt of your order (view details here). Each optic we make is custom-sized, so no shopping cart is required. Worldwide express shipping is also available.
