Setting up an interferometer: alignment without the frustration
A step-by-step routine for getting clean fringes on a Michelson setup the first time.





Since 1962, our engineers and craftspeople have manufactured educational and scientific apparatus in Ambala Cantt — the instruments hub of India. Every design is refined on our own benches before it reaches a classroom or research lab.
Apparatus designed around how physics is actually taught and measured.
Optics, electronics and mechanics handled under one workshop roof.
ISO 9001 processes, calibration checks, and a warranty on every unit.
Built and inspected to a consistent standard, order after order.
Delivery schedules we commit to and keep.
Engineers who understand the apparatus they make.
Support from enquiry through installation and beyond.
A step-by-step routine for getting clean fringes on a Michelson setup the first time.
Ballistic vs spot vs moving-coil — how sensitivity, damping and range should guide your pick.
Send a quick inquiry and our team responds with pricing and availability within one business day.
"Our spectrometers have taken a decade of student use and still read true. Servicing is quick and honest."
"Full lab set-up delivered on time with itemised catalogue numbers — made our tender paperwork simple."
