The comparison of current optical manufacturing methods and prior to year 2000

Abstract :

Prior to Year 2000

Optical components such as Window, filters, wedge , mirror , Prisms , cylinder .. They require many kind of machineries , tools , ingredients and lengthy process.

Example 1 : For a 3 sides precision right angle prism ,Material = NB-K 7

Seq 1 Material Blank

Seq 2 Blocking +Milling+ Rough Grind+ Fine Grind +Slurry Polish+ Finishing Polish + Inspection

Seq 3 Repeat Seq 2

Seq 4 Repeat Seq 2

Total process time ...... 100 hrs for qty of 20 Cycle time = 6 weeks

Required : High skill work force

Final Spec = Surface Figure 2 Lambdas, Surface Quality 20-10 Mil, Angle tolerance +/- 5 minutes.

Example 2 : 7.75 mm , 8 mm diameter Laser Mirror

* The used of Cluster Molded Blanks,.

* E-beam coating

After Year 2000

With more understanding the effects of the diamond tools, the application of using the CNC machine to optics

has simplified the optical fabrication process and also has eliminated the used of special machines and tools.

Example 1

Seq 1 Material Blank

Seq 2 CNC Shaping

Seq 3 Rough Polishing

Seq 4 Precision Polishing

Total process time ..... 40 hrs for qty of 20 Cycle time = 3 weeks

Required : Skill Work force

Final Spec = Surface Figure Lambda/20, Surface Quality 10-5 Mil, Angle tolerance 5 arc seconds

Example 2 :

* Molded finished Optics

* Free form shaping

* Free form polishing

* Iron Bean Sputtering Coating
