In order to measure light, you first need the mechanical hardware and optics to detect, mask, reflect and refract it.
At TitanLabs, we’re developing tools that represent significant improvements on the equipment currently available in the market. Following is a description of one of those improvements.
Indexed Multiple Slit Slider (IMSS)
The IMSS is our first product in this area. The assembly is designed to be mounted to a ThorLabs XYR1 stage (https://www.thorlabs.com/thorproduct.cfm?partnumber=XYR1) giving it the ability to rotate and translate in the X and Y plain. It also offers:
Most streak cameras and spectrometers use a continuously adjustable slit, which typically consists of a housing within which two blades are held in a mechanism. The blades can be opened or closed with an adjustment knob. Often there are markings on the knob that give an indication of the approximate slit gap. However, it is difficult to know the exact size of the gap without inserting a feeler gauge.
In addition, springs can degrade causing the slit blades to lose their parallel nature. Finally, changing fixed slit models requires time-consuming bolt removal and installation.
The Indexed Multiple Slit Slider (IMSS) includes a slit mask. This mask consists of a thin metal plate with several laser cut, fixed width slits with corresponding width markings. The carrier is designed to fit snugly inside the holder/base. The ball and socket indexing system ensures the center-line for each slit arrives at the same location in the entrance to the holder/base.
In addition to streak cameras, this system could be used for
Spectrometer, x-ray pinhole cameras (replace slits with pin holes), scanning slit of panorama camera, etc.
The following products are in development.
