Precision instruments, metrology, fluorescence, low-noise analog electronics – that’s what we do.
Cornea Glare Test Instrument For MEEI
This custom built instrument will allow Dr. Rony Sayegh at the MEEI (Mass Eye and Ear Infirmary, Boston, MA) to improve the sight of his patients.
Blue LEDs Make Healthy Babies – Firefly Phototherapy From Design That Matters
At an early stage in this project, Pete provided measurements and guidance about the most effective LED optics for the jaundice cure for new born babies.
Eye Exam Using a Smart Phone, And Some Plastic Optics – The NETRA Project
Pete has been working with some folks at the MIT Media Lab, in particular the Camera Culture Group of Ramesh Raskar.
Energy Harvesting – Battery-Free Radio
We’re working on some energy harvesting projects – and we learned about this amazing project – a radio powered only by the sound of the voice of the person talking at the transmit end.
Photos of Recent Work
Here’s a photo of an LED light source and image projector under test
In The Future, Robots Will Have Arms
The kind of arms to pick up things, not like the puny arms that a T-Rex has.
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.
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.
Prototype, Progress, And The First Digital Camera
We make prototypes. Sometimes it’s hard to imagine how a product will evolve from the first (clumsy?) prototype into a sleek product, once it gets ‘real’ and becomes a manufactured (perfected?) item.
