JNS Glass & Coatings produces a wide array of custom optics. JNS has an extensive inventory of optical parts on hand that may help narrow down our customer’s needs.

Custom Optical Windows
JNS Glass & Coatings optical windows are glass or plastic components that typically shield a lens, sensor or lighting system from debris, dust and the force of impact. Aside from stock components, JNS routinely manufactures these windows and covers on a custom basis to various sizes and configurations. JNS often coats these optical windows with additional coatings such as anti-reflection, hydrophobic, oleophobic, and scratch resistant .
Optical Bandpass Filters
JNS Glass & Coatings specializes in producing custom optical windows and optical bandpass filters. JNS stocks a very wide range of optical bandpass filters for machine vision and industrial imaging applications. Aside from standard filter designs and mounting configurations, custom filters can be made according to customer-supplied specifications for requirements ranging from prototype to high volume OEM needs. JNS capabilities extend over the entire spectrum of filter products that we offer, including bandpass, longpass, shortpass, notch and dichroic filters.
Spherical Lenses
JNS Glass & Coatings’ spherical lenses are manufactured on a custom basis if not currently in inventory. Plano-Convex, Bi-Convex or Positive Meniscus (positive focal length) lenses and Plano-Concave, Bi-Concave or Negative Meniscus (negative focal length) lenses are routinely fabricated. JNS routinely applies anti-reflection or other custom optical coatings to the lens surfaces.
Optical Beamsplitter
JNS Glass & Coatings beamsplitter material is inventoried in various sheet thicknesses for specific wavelength ranges from visible to IR, and in various transmission/reflection ratios. A typical application for this mirror is industrial imaging. This beamsplitter mirror is typically applied to a double side polished glass appropriate for imaging. A second-side anti-reflection coating is normally recommended and thus is offered as standard. For larger sized beamsplitter applications such as teleprompters, flight simulation, holographic displays, please visit beamsplitter glass.
Multi Element Lenses
Multi-element lenses are manufactured my JNS Glass & Coatings on a custom basis for a wide variety of end users and applications. Typically JNS works with designs and drawings supplied by the customer. This category includes cemented achromatic doublets and lens assemblies mounted in aluminum or plastic housings. (Note: JNS has the ability to custom engrave the housing with company name and or logo. Please contact us to learn more about this service.)
Wedges
JNS produces wedges of custom sizes, shapes, angles and configurations. A wedge is a specific type of prism used to deviate light in a specific direction by a predetermined angular amount or distance. They can be used singly or in pairs as a fine-tuning adjustment to steer or align a beam of light. JNS regularly coats wedges with custom optical coatings such as anti-reflection coatings.
Optical Mirrors
JNS carries enhanced aluminum and dielectric mirror sheets in various thicknesses and types. Mirrors are typically fabricated according to customer specifications. More durable, high-efficiency dichroic reflectors (sometimes referred to as dichroic beamsplitters) are also available to reflect desired wavelengths while passing other light. JNS stocks visible-near IR, red, green, blue, near-infrared (hot mirror) and visible (cold mirror) reflectors which are sized to specified requirements. In addition to flat sheet materials, the above can be supplied in right angle (prism), concave, convex and many other configurations.
Cylindrical Lenses
Cylindrical lenses have their power or magnification in only one axis or direction, and can be custom manufactured with positive or negative focal lengths. In machine vision applications they are commonly used in conjunction with LED line lights or laser diodes to generate a well-defined band or line of light.
