Precision instruments, metrology, fluorescence, low-noise analog electronics – that’s what we do.
Arduino Motor Control
We’re using some Arduino boards for a variety of projects – to run the motion stage (25um resolution), to test LED colors, to run an oven for testing temperature compensation electronics.
Nixie Tube Tester
Recently we started working with David O’ Brien, whose list of accomplishments is too long for this single posting.
Lens Testing – Our Precision MTF Test Jig
Recently we designed and built a precision motion stage capable of focus adjustments to about 0.5um.
Low Noise x1000 Amplifier
Here’s the specs: Voltage noise 2.5nV/√Hz, Gain 1000, bandwidth 0.3Hz to 500kHz.
Frequency Compensated Attenuator Tests Amplifiers
We’re working on a low-noise amplifier product, and to test it we need some attenuation, to generate clean low-level signals. The pdf shows a schematic and describes some test results.
Photos of Mechanical, Front Panel Design
Portable electronic instruments. These photos show knobs, nuts, knurled, and know-how (Pete’s).
Light Uniformity Testing
For both a clinical test microscope, and a home theater HDTV projection display, the light from the source must be quite uniform.
Custom Front Panels
Here’s a vendor we recommend, and a photo of some parts they made for us.
Image Analysis With (Free) ImageJ Software
Lately we’ve been able to use our digital camera to perform some nice measurements, through the help of a program called ImageJ.
