The details may be varied substantially without departing from the spirit of the invention, and exclusive use of all modifications which are within the scope of the appended claims is reserved. We Claim

1. The Optical Resolution & Focusing with Collimation Apparatus is assembly of different mechanical item which in combination act as holding fixture for optical checking & focusing operation of the assembly for test piece, the said apparatus comprises of following :
- Base, is rectangular plate with one hole at right side on center line to hold the apparatus.
- Rod, is vertical stand in which all other item of said apparatus assembled.
- Collar, cylinder type of design with hole at one side. This one is responsible to hold the y-axis motion of apparatus at fixed position.
- Bush, is a plate with clip type hole to provide easy movement rod with tight griping.
- Holding Rod is horizontal rod with small slot at one end.
- Holding Plate is rectangular shape plate with small handle type arrangement.
