Optomechanics

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:

  • The ability to use Microscope Slide resolution targets and calibration masks to set up the camera
  • Slit Width clearly printed on the mask for easier reference
  • Taped holes that can be used to mount experimental hardware (e.g. a fiber array, etc.)

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.

TitanLabs Leaver Lock Post Holder

  • The ability to know if the post is loose or tight simply by glancing at it
  • A constant pressure on the post during adjustment, regardless of the locking mechanism position
  • The ability to vary the post holding pressure
  • Ability to know that optimal clamping pressure is applied with a glance
  • A lever arm to provide more mechanical advantage when locking
  • The elimination of damage or rotate posts when locking
  • A large clamping area ~.23 square inches.
  • Only one smooth motion is required to engage the locking mechanism

The advantages of this product relative to the New Focus 9601 cam lock post holder are:

  • With TitanLabs Lever Lock Post Holder, a post can be inserted with one hand/ one motion. The NewFocus 9601 requires two hands to insert the post
  • Since our locking mechanism is independent of the holding pressure mechanism, there is no chance of accidentally relieving pressure on the post while turning the locking knob

Other products in this category include

  • Interlocking light shield
  • Key Lock Washer capture base plate.
