UV-VIS-NIR Accessories

BaySpec supplies all the accessories necessary to make sure your UV-VIS-NIR system is perfectly integrated into your application. Click the Full Details below to see the variety of accessories, from miniature probes to sample holders, that will help you get the most out of your system.

Probes
A variety of fiber probe designs are available, customized to your specific application. Available designs include a standard lens-based handheld probe for standoff or contact measurements, dip probes for immersion in liquids, miniaturized bundle probes for contact measurements, and miniaturized standoff probes with options for multiple wavelengths or modalities.

— Dip Probes
These assemblies can be immersed into a liquid 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 reflected off of a mirror to pass 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 threaded, replaceable tip.

Optical Adapters
These adapters are designed to fit onto a connector or custom termination, or can be designed to mount onto a piece of equipment. Their purpose is to image or collimate the light from the fiber(s), or to focus light onto the fiber(s) from a light source. Generally they consist of a machined part with the optical element mounted in place, with or without a focusing adjustment. Optical adapters also consist of vacuum feedthroughs where optical testing is performed through a chamber wall. This can be accomplished using a variety of modified vacuum flange designs, such as the standard conflat flanges which are available. The fiber assembly is sealed using Varian Torr Seal and may include a lens to collimate or capture the signal.

Hardware Adapters
This product class generally contains no optical components, but can be used for mounting fiber assemblies to a piece of equipment, to another fiber assembly, or for enclosing optical components or assemblies. Standard adapters include those which mate SMA, FC, ST or any other standard connector to another connector. Other custom adapters are generally made specifically for OEM clients and their applications.

Jumpers
Commonly called jumpers or patchcords, these basic fiber assemblies range from more generic datacom jumpers to the single fiber, large core cable designs utilizing more robust and customized components. Optical coatings to lower the reflection (AR coating) or to create a cutoff wavelength can be added to the fiber, as well as any multi-fiber assembly. We also offer high power SMA’s using SS or copper ferrules which have an air pocket surrounding the front of the SMA ferrule, as well as an aluminum or copper heatsink to pull the thermal energy away from the fiber.

Bundles
A fiber bundle assembly is used for transporting light from extended sources using more than one fiber, up to thousands of fibers. The style of termination on each end may be 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.

The fibers can be arranged into round, ring, a single line or a multi-segment line or arc, or packed into 2D shapes and arrays. V-grooves in the base material are commonly used for interfacing to diode lasers and can be AR coated to maximize light throughput.

Bifurcated Bundles
These assemblies are the same as bundles, but either one side or both sides of the assembly can be separated into a multiple 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 and are available with various fiber distribution designs from one end to the other.

Bundle assemblies using SM, 50 or 62.5um core fibers generally made for datacom applications are commonly called harnesses and use standard datacom connectors such as FC, ST, LC, SC, MTP, MT-RJ, etc. for short assemblies
