The FTIR spectrometer design is based on the Michelson Interferometer, featuring: 1. 850nm Laser Source: Provides a coherent light source for generating interference patterns. 2. ZnSe Beam Splitter: Divides the incoming laser beam into two paths, directing them towards the retro reflector mirrors. ZnSe, while limiting the spectrometer range, is not humidity-sensitive like KBr. 3. Retro Reflector Mirrors: Reflect the split beams back towards the beam splitter, ensuring the paths of the two beams recombine. 4. Visible Detector: Monitors the interference patterns created by the laser.

JASPER: Peltier Cooler for Lasers

In the world of precision laser applications, maintaining optimal operating temperatures is crucial. Our latest project focuses on developing a Peltier cooler for Diode-Pumped Solid-State (DPSS) lasers, which require a stable temperature range of 20 to 25 degrees Celsius for optimal performance. TEC controllers employ mostly a buck-boost regulator to control bi-directional current and need a digital PID controller to ensure the temperature is stabilized within a short span with minimal ringing and overshoot. We will be developing a GUI to help set the required temperature, tune the PID parameters, and visualize the way the temperature stabilizes.
