Fiber Pigtailed Fabry-Perot Etalons consist of a solid or air gap etalon, collimating lenses and input/output fibers. They can be made for different spectral window (UV, VIS, IR) dependent on the specific application. The solid etalon is made of optical quality glass (fused silica, BK7...) while air spaced etalons are built on Zerodur frame.
The faces are highly polished in order to achieve very good flatness and parallelism. They are coated with dielectric thin films to assure high finesse and transmission. The etalons are subsequently aligned with optical axis of collimators and fixed on the housing by a low shrinkage optical grade adhesive. This device acts as a narrow bandwidth filter with series of transmission peaks uniformly spaced in frequency domain. They have better spectral resolution and constant FSR than fiber based Fabry-Perot etalons. In applications where temperature stability is critical, air gap etalon offer better thermal stability. See PDF for more on basic of Fabry-Perot interferometer. Fabry-Perot Etalons are use in telecom systems as narrow band filters to lock a laser cavity on a fixed frequency. They are also used as a frequency reference according to ITU grid and in other applications such as optical telecommunication, optical sensing and others.

Precision Photonics offers superior quality mirrors and coatings at a great value. We use only ion-beam-sputtered (IBS) coatings because IBS coatings are significantly more dense, durable, and rugged than conventional e-beam or ion-assisted evaporated coatings. Compared to other coatings, IBS coatings also offer lower scatter and absorption losses and fewer pin-hole defects in the coated surface. This superior film quality and uniformity results in environmentally stable optics with laser damage thresholds of >40 joules at 1064nm.
The SBB super broadband mirrors are ideal for beam-steering applications using both the fundamental laser wavelength and one or more harmonics within the same beam path. Because it is an all-dielectric design, they can handle the high laser powers of both CW and pulsed systems, without limiting the useful angle of incidence or sensitivity to varying states of polarization.
The MPM mirror has been specially designed for multi-photon applications requiring high reflectivity, broad bandwidth, low dispersion and high transmission in the visible spectrum. All our laser mirrors are ion beam sputtered; thus the coatings are dense, easy to clean and insensitive to moisture.

These laser mirrors are designed for specific wavelength laser applications where low wavefront distortion, low scattering, and high reflectivity are usually important. The reflectance is greater than 99.5% at the specified wavelength. Typically the s-polarization is greater than 99.9% and p-polarization is close to 99.5%.
Possible surface damage from higher power laser beams is minimized by careful polishing and precisely controlled coating methods.
As with the broadband mirrors, standard diameters are 1/2 inch, 3/4 inch, 1 inch and 2 inches. Other diameters are available on request. Other laser wavelengths can also be provided so please call.

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.
