At Spectraconn Inc, we work with your buyers and engineers to manufacture products to meet your fiber optic and budgetary requirements. Our fiber optic cable assemblies can be used for applications including, but not limited to spectroscopy, DPSSL delivery, materials processing, pharmaceutical, medical applications and process control.

Some applications can utilize standard fiber optic sizes, numerical apertures (NA) and materials. However, many applications require fibers to have a different NA, temperature rating, core/clad ratio and wavelength range, as well as more specialized terminations and jacketing. We can meet these design criteria and provide you with assemblies ranging in volume from prototype or one-of-a-kind designs, to larger scale OEM orders.

Assemblies can be made with singlemode or multimode fibers with graded-index or step-index cladding structure. Secondary buffers and jacketing include industry standards as well as more specialty choices designed to meet more demanding application requirements for custom fiber optic assemblies.

At Spectraconn Inc, we look forward to forging a strong relationship together and providing you, and your customer, with a competent and reliable source of quality products to meet all of your fiber optic objectives.

Efficiently transferring UV-VIS-NIR energy from point A to point B, while maintaining the highest level of quality control, reliability and confidence in our products, is our objective and allows us to provide the link to your success!

A bundle can be thought of as a jumper assembly, but with many more fibers, and a virtually unlimited number of options available for fiber types, cable materials and end terminations. Many of these bundles may contain some of our standard types of terminations. However, many products are OEM based and therefore require a specific design that can be manufactured by one of our top quality suppliers to our exacting standards.


Dip Probes

These assemblies are immersed into a solution in order to obtain spectra of its constituents and are commonly referred to as a Dip Probe or a Transmission Probe. The basic design consists of two fibers with a lens that collimates the light from one fiber through an open section through which the liquid can pass. The light is then reflected off of a mirror where it passes through the liquid and lens a second time, and is refocused onto the second fiber for transmission to the analyzing instrument. For the standard probe design, the liquid absorption pathlength is double the physical opening of the replaceable tip. Other designs may call for larger probes or more robust probes designed to meet harsher conditions.


Furcated Bundles

These assemblies are the same as bundles, but either one end or both ends can be separated into a countless number of standard or custom-designed terminations and fiber configurations to match the physical and optical characteristics required at the terminations. These assemblies can be used to split or combine optical power. The only limitation is that the number of fibers per furcated leg must be at least one!


Jumpers – Large Core

Commonly called jumpers or patchcords, these basic fiber assemblies range from more generic datacom jumpers to single fiber, large core cable designs utilizing more robust and customized components. Optical coatings to enhance the fiber’s properties of minimized reflection or cutoff wavelengths can be added for jumpers, as well as any multi-fiber assembly. We also offer high power SMA's in several versions.


Optical Adapters

These adapters are designed to fit onto a connector or custom termination, or can be designed to be mounted onto a piece of equipment. Their purpose is to image or collimate the light from the fiber(s) or from a source to the fiber(s). Generally they consist of a machined part with the optical elements mounted in place, with or without focusing adjustment. Optical adapters also consist of vacuum feedthroughs where optical testing through a vacuum chamber is desired. This can be accomplished using a variety of modified vacuum flange designs, such as the variety of conflat flanges available, and an internally sealed fiber and/or optics.
