Objective Assembly parts diagram: 1 objective doublet, 2 objective bell, 3 lens retaining ring, 4 lens spacer ring, 5 o-ring set. 5 parts in 5 top-level items. — Objective Assembly parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Objective Doublet	1×	Cemented achromatic doublet, typically 50 mm in diameter with multilayer anti-reflective coatings, that forms the primary image.
2	Objective Bell	1×	Flared aluminium housing threaded onto the main tube that holds the objective doublet at the correct spacing.
3	Lens Retaining Ring	1×	Threaded ring that clamps the objective glass against its seat without inducing stress birefringence.
4	Lens Spacer Ring	1×	Precision-ground ring that sets the air gap between lens elements to the optical prescription.
5	O-Ring Set	1×	Objective seal
