Optical Manufacturing Capabilities: Diamond Turning, CNC Grinding, Polishing, Centering, and Metrology

Cimcoop operates seven core optical manufacturing processes in a single vertically integrated facility: single point diamond turning (SPDT), CNC grinding, CNC polishing, pitch polishing, CNC centering, cementing and varnishing, and precision metrology. The facility handles optics from 1 to 200 mm diameter across infrared and visible materials. Every process is ISO 9001:2015 certified with full traceability, and every shipment includes certificates of conformity and metrology reports.

Seven core processes. One vertically integrated facility. Every step in-house — from raw crystal to finished, inspected optic.

Flagship Capability
01

Single Point Diamond Turning

Single-point natural diamond tools producing optical surfaces with nanometer-level precision. SPDT enables complex surface geometries impossible with conventional grinding — the cornerstone of our IR optics manufacturing.

Surfaces: Spherical, aspherical, diffractive, and freeform
Diameter range: 1 – 200 mm
Materials: Silicon, Germanium, ZnS, CaF₂, plastics, non-ferrous metals

02

CNC Grinding

Computer-controlled grinding that shapes spherical and flat optical surfaces on crystalline and glass substrates. The foundation of our surface generation process.

Surfaces: Spherical and flat
Diameter range: 10 – 150 mm
Materials: Silicon, Germanium, optical glass, fused silica

03

CNC Polishing

Consistent, repeatable spherical surface finishes on optical glass and fused silica. Computer-controlled tool paths ensure tight form accuracy across production runs.

Surfaces: Spherical polishing
Materials: Optical glass, fused silica
Quality: High surface quality with tight form accuracy

04

Pitch Polishing

A traditional craft technique unmatched for surface form quality. Skilled opticians working with carefully prepared pitch laps — for when no compromise on form accuracy is acceptable.

Technique: Traditional craft pitch lap polishing
Result: Supreme surface form and quality
Application: Most demanding surface requirements

05

CNC Centering

Precise alignment of optical and mechanical axes. Diameters up to 200mm with ±0.01mm tolerances — including truncated shapes and stepped geometries for complex assemblies.

Max diameter: Up to 200 mm
Tolerance: ±0.01 mm
Features: Truncated shapes and steps

Cementing & Varnishing

Assembly of multi-element optical groups — achromatic doublets, triplets, and cube beam-splitters. Zoom camera-equipped varnishing stations for uniform, defect-free edge coatings.

Assemblies: Achromatic lenses (doublets and triplets)
Components: Cube beam-splitters
Varnishing: Zoom camera-equipped varnishing stations

Frequently Asked Questions

What manufacturing processes does Cimcoop perform in-house?

Cimcoop performs seven core processes in-house: single point diamond turning (SPDT), CNC grinding, CNC polishing, pitch polishing, CNC centering, optical cementing and varnishing, and precision metrology. All processes are under one roof with zero outsourcing.

What is single point diamond turning?

Single point diamond turning (SPDT) is an ultra-precision machining process that uses a natural diamond tool to cut optical surfaces with nanometer-level precision. It enables complex surface geometries — aspherical, diffractive, and freeform — that are impossible with conventional grinding.

What metrology equipment does Cimcoop use?

Cimcoop's climate-controlled metrology lab includes Taylor Hobson PGI Dimension 3XL surface profilers, Zygo ZeGage white-light interferometers, autocollimators for angular measurement, FTIR spectroscopy, and UV-VIS spectrophotometry.

What is the maximum optic diameter Cimcoop can produce?

Cimcoop's diamond turning and centering platforms handle optics up to 200 mm in diameter.
