Ocean Optics HR4000, HR2000, HR2000+ fiber optic spectrometer (HR2000CG-UV-NIR)
The broadband CG spectrometers use the HC-1 grating--a revolutionary grating with variable blaze wavelength, specially designed to provide a spectral output range of 200-1100 nm. Each CG series spectrometer has a 5 micron entrance slit, the patented HC-1. All CG series spectrometers use the HC-1 grating--a revolutionary composite grating, providing a spectral output range of 200-1100 nm. (See the HC-1 grating efficiency curve on the right). In addition to this composite grating, each CG series spectrometer has an OFLV high-order diffraction filter to eliminate the effects of second and third order diffraction. The grating and OFLV filter are installed and fixed in place during manufacture. The HR2000+CG is the only CG series spectrometer that allows full spectrum scans to be captured and stored into memory per second (when the spectrometer is connected to a PC via the USB2.0 port). The HR2000+CG is ideal for applications requiring fast response and high resolution monitoring. This innovative combination also created our fastest spectrometer - one scan per millisecond. The HR4000CG and HR2000+CG have a portable programmable microcontroller, providing flexible control of the spectrometer and accessories. By using a new 30PIT connector, you can execute many operating parameters in software, including controlling external light sources and retrieving data from external targets. There are 10 programmable data I/O interfaces to connect with other devices; one analog input and one analog output; a pulse generator to trigger devices. The HR2000CG does not include I/O, analog channels or a pulse generator

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
