Optical Parallels

We are the only manufacturer & suppliers of Optical Parallels in india. Optical Parallels are used for checking Flatness and Parallelism of Micrometer measuring faces. These are supplied as a set of four numbers with thickness increment of 0.125 mm (one fourth of the pitch of the Micrometer). Optical Parallels are made from Fused Silica/Fused Quartz material as the material has environmental durability, and a low coefficient of thermal / Linear expansion and as well resistant to abrasion.

The parallels are manufactured to comply with the NPL (National Physical Laboratory) specification MOY/SCMI/54
