Fiber Optic Spectrum Analyzers
Miniature Spectrometers
For Lasers, Laser Diodes, and LED
These instruments are used to measure wavelength emissions from Lasers, Laser Diodes and LED's into the near infrared. A fiber optic cable is used to couple the output from the test device into the spectrometer. The instrument allows characterization of the wavelength stability with time, temperature, and device drive current. Depending on your application and wavelength requirements, StellarNet can offer high resolution spectrometers up to 0.1nm resolution. Contact StellarNet for availability of other wavelength range and resolutions.
Optional Configurations
Multi-channel systems for continuous monitoring of several devices are easily configured by daisy chaining additional units.
Optical Fibers
For 1310 and 1550nm laser diodes, a fiber is used to couple the ST device connector with an XNIR2 spectrometer input connector (SMA). Other couplings use a 400um fiber with a lens attached to a SMA bulkhead fitting that can be easily mounted in the device emission path.
Cosine Receptors
The CR1-UVN is a ½"diameter near cosine receptor using sanded fused silica diffuser for 200-1700nm. Has reduced 90° FOV and low 7% loss
