JML Optical is a leading designer and manufacturer of precision prototype optics and optical systems for hundreds of domestic and international customers. Production for prototype optics always starts in Rochester where our staff begins the process by analyzing requirements and creating compliant optical designs. JML has also forged strong partnerships with numerous Pacific Rim manufacturing companies. Such alliances have enabled JML to expand its ability to mass manufacture unique and prototype optics for many customers in a cost and time effective manner.

Many opto-mechanical assemblies require windows because they must be housed in controlled environments. Because the windows must not degrade the quality of the laser beam, engineers specify precision plano elements for the task. Windows provide optical access to a sample or device that must operate inside the chamber of the opto-mechanical assemblies, which is usually made of thick aluminum or steel. For instance, laser diodes must be protected from dust and moisture, so manufacturers hermetically seal them in metal housings and use a window to allow the laser beam to propagate through the opto-mechanical assemblies.

A segmented lens is a closely spaced, often cemented, combination of positive and negative elements with differing refractive indices. These elements are chosen so that chromatic aberration is cancelled at two distinct, well-separated wavelengths. These wavelengths in the segmented lens are usually selected to fall in the red and blue portions of the spectrum. A single focal-length value’s applied to the entire visible spectrum. By comparison, the focal-length difference for a BK7 singlet between these same red and blue wavelengths is typically 30 or 40 times larger than that of a segmented lens.

The anti reflective coating is designed to reduce the amount of light lost to reflection at the surfaces of individual, transmissive elements. Historically, motivation for the development of the anti reflective coating came from problems with loss of light and ghost images in compound, multi-element lens systems. They experience refraction as if they emanated from the object; however, since they were created inside the lens itself, they produce strange patterns in the image plane. Ghost images can be controlled in several ways, but application of the anti reflective coating accomplishes the task most effectively.

Reflective coating absorbs some of the light not reflected by the thin films. This "lost" light is converted to heat through interactions with the atomic structure of the coat. Another fraction of the "lost" light is scattered by microscopic surface texture and impurities in the reflective coating. The remaining fraction of "lost" light travels completely through the coat, to be absorbed or scattered by the underlying substrate. Small improvements in a mirror’s reflectivity can have dramatic impact upon the performance of a system with reflective coating.

Achromat lens doublets are used as telescope objectives, eye loupes, magnifying glasses and eyepieces. The origin of the technical term "achromatic" is in the color-corrected performance of compound lenses. The optical performance of compound lenses, two or more single elements designed to work together, is superior to that of a single acrhomat lens elements working alone. These lenses can be found in a wide variety of instruments. Since the development of the laser, doublets have also been used to focus and manipulate laser beams because their image quality is superior to that of achromat lens singlets.
