MARK4 ANTI-Reflection device
designed to fit 60mm modles; features scores of tiny, light transmitting honeycomb baffles that reduce lens glare without obscuring sight
An item specifically designed to be placed over the optics to prevent the reflection of light off the lens of items such as binoculars, telescopes for gun sights, rifle and other weapon sights in the visible and thermal ranges, vision blocks and laser-protective goggles. the item's design of a honeycomb material with special anti-reflection coating provides protection from glint and glare from optical surfaces without effecting the view. the item may include a flip-open cover designed to protect the filter. packaging components such as carrying bag or case, and instruction for installation may also be included.
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Item does not contain precious metal.
No known electrostatic discharge (esd) or electromagnetic interference (emi) sensitivity.
Represents items with no adp components
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
