| Surface Quality |
80/50 per MIL-O-13830A is standard. |
| Humidity Resistance |
MIL-STD-810C; Method 507, Procedure 1 |
| Documentation |
A measurement of the pass band region is provided with each
filter lot. Blocking verification to optical density (OD) 5 is performed
on a Cary 500 UV-VIS-IR Spectrophotometer for an additional charge. Spectral
data in ASCI spreadsheet format can be sent via E-mail. |
| Scribed Filters for long life |
To ensure Maximum Life Knight Optical filter coatings are
scribed and hermetically sealed to block out 100% of moisture and humidity
while in storage at Knight optical. With the use of moisture resistant
sealant, filters are then sealed prior to shipment. These two features
ensure maximum lifetime and quality. |
| Scribing |
In order to scribe, the thin film is removed from around
the circumference of the individual filter. This allows a glass to glass
seal that ensures an epoxy seal. This method eliminates delamination or
performance due to humidity. |
