Window Coatings

• Anti-reflection (A.R.) coatings: Apply these type coatings to achieve the maximum depth of field decoding range and to improve the possible pitch range of acceptable window angles and positions. A.R. coatings also have very poor abrasion and scratch resistance; making only single-side AR coating most practical (the AR coated side of the window typically faces the interior of the imager module).
|
| |
|
+ |
• Anti-scratch coatings: Apply Polysiloxane type coatings to plastic surfaces to improve the surface resistance to both scratch and abrasion.
