Product Name:Optical Components
Title:Advanced Optical Components
RAMP produces, polishes, coats and assembles many types of optical components for missiles, FLIR imaging systems and other components for military and industrial uses.
 
Main Products and Applications:
ZnS Component Production
RAMP is a leading producer of domes, windows and lenses of high optical quality Zinc Sulfide (ZnS) used in FLIR imaging systems and in various missiles. Material can be supplied as domes or plates in sizes up to 600 x 300 x 15 mm. Polishing and coating are also available.
Transparency is extended to the visible light range by applying hot isostatic pressure (HiP) treatment to the raw material.
 
Advanced Optical Coating Center
RAMP's optical coating center offers optical system manufacturers a full range of services from feasibility studies and definition of specifications, through advanced design and prototype development, to full scale production, including testing and QA. We specialize in precise polishing and coating of optical components designated for use in the spectral regions from the UV range to 8-12 microns.
 
Coatings - Main Products and Services:
Our extensive experience and supporting facilities yield state-of-the-art products. Coating is available for all types of optical elements: windows, lenses, visors and domes. Substrate materials include:
  • Quartz
  • Si
  • Ge
  • ZnS
  • ZnSe
  • CaF2
  • Plastic substructures
  • Other materials
Products and Services Include:
1. Environmental protection of external and
airborne windows and domes:
  • Anti-reflective coatings
  • Rain erosion protective coatings
2. Superior performance transparent conductive coatings for
VIS, NIR 3-5 micron, 8-12 micron and dual band coatings.
3. Coatings for IR detectors:
  • High performance filters and anti-reflective coatings on dewar windows
  • Low temperature filters
  • Absorbent coatings
4. High durability protected silver mirrors for
VIS and IR regions
5. Multispectral coatings
  • Dichroic mirrors
  • Anti-reflective coatings
  • Transparent conductive coatings
     
Improved coatings using ion assisted deposition process Coatings of elements up to 50 cm in diameter.
Our major processing equipment includes coating chambers (for elements up to 12" diameter). We utilize a wide variety of deposition techniques such as Resistance, E-Beam guns and Ion Assisted.
Our testing facilities include UV, VIS and IR spectrophotometers, Optical and SEM inspection instruments, environmental durability test chambers. An optical polishing workshop is available in-house.
 
Replicated Optics
Replicated optical components are produced by transferring an optical surface to a desirable substrate without the need for high precision polishing. RAMP's Replicated Optics Laboratory has developed a wide range of processes to produce highly precise mirrors (P-V l/20). Surface quality is 10A RMS in the IR, visible and UV Ranges.
We offer mirrors on a wide variety of substrates, from metals, through ceramics, to composite materials integrated with the system's mechanical interfaces. This means more flexibility in the optomechanical design and production, increased reliability and cost-effectiveness. RAMP mirrors meet the durability requirements of MIL-M-13508 and
MIL-C-48497A for temperature endurance and humidity.
 
Optics Assembly Center
The Optical Assembly Center provides precise optomechanical and electro-optical packaging and assembly services with capabilities from design and development to full-scale production.
We offer
  • EMI / RFI shielded window assemblies
  • Thermo-mechanical stress-free mounting and bonding, to minimize optical distortion
  • Metal-to-glass (or other optical materials) sealing up to 10-9 ccHe/STP.
  • Optical cementing of components - with cements transparent in the various spectral ranges, using precise alignment techniques.
  • All lines are supported by our optomechanical and materials engineering experience, including full optical and material testing capabilities.
Composite & Plastic Components
for Optical Assemblies
 
Lens Holding Tubes
RAMP offers design, development and production of lightweight, high dimensional stability composite lens holding tubes for optical systems. Our holding tubes match thermal expansion coefficients to the system requirements. Components can be reinforced with graphite, carbon, glass or aramid fibers in order to achieve optimal mechanical and thermal performance. We offer production, testing and QA capabilities.
 
Advanced Plastics for Optical Components
RAMP offers optical components made of high quality / high heat resistant plastics using direct injection or injection compression molding. We also offer optional vacuum metalizing, and filtering, anti-reflective and anti-scratch coatings.
