Standard Compression Ring Set
Standard Compression Ring Set (Product Code: SLE/M/68) is a set of 5 injection-moulded polymer rings used to make an eyepiece adapter grip eyepieces of different outer diameters, covering eyepieces from 39 to 60.75 mm. Choosing the matching ring gives a snug, centred hold, so an attached camera or viewing accessory stays aligned while images are taken. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory equipment supplier for India and overseas buyers.

What Is the Compression Ring Set Used For?
An eyepiece adapter only works well if it clamps the eyepiece firmly and squarely; a loose fit lets the camera tilt, which shows up as dark edges, off-centre images or blur. Compression rings fill the gap between the adapter's clamp and the eyepiece barrel, so one adapter can be moved between instruments whose eyepieces differ in outer diameter. Labs that photograph slides for records, displays or student projects use them to get a stable, repeatable set-up on each microscope.
Measure the outer diameter of the eyepiece where the adapter will clamp, ideally with a vernier caliper, then try the closest ring: it should slide on with light pressure and not rock. Tighten the adapter clamp only as much as needed to hold the ring. Keep the unused rings in a labelled bag with the adapter so the right size is always at hand.
What to Specify When Ordering
- Outer diameter of the eyepieces you want to fit, within 39 to 60.75 mm
- Type or model of eyepiece adapter you use
- Number of ring sets, one per adapter
