Precision instruments, metrology, fluorescence, low-noise analog electronics – that’s what we do.
Infrared CO2 Measurement
These notes describe the opto-mechanical engineering I contributed to a Pellistor that can detect elevated levels of CO2 in the air.
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.
Photos of Recent Work
Here’s a photo of an LED light source and image projector under test
Lens Testing – Our Precision MTF Test Jig
Recently we designed and built a precision motion stage capable of focus adjustments to about 0.5um.
Microscope Objectives – NA, Cost, And Parabolas
We were looking at various microscope objectives – those lenses on the turrets that aim toward the slides.
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.
Radiometric Measurements
It’s easy to confuse the units of LED light output. Steradians, luminous intensity, etc.
