Andover Corporation’s Role in Laser-Based Technologies Across Industries

From battlefield precision to breakthroughs in quantum communication, laser-based technologies are revolutionizing every industry they touch. At the core of these innovations are high-performance optical filters and coatings-critical to controlling, directing, and protecting sensitive laser systems. With decades of expertise and vertically integrated manufacturing, Andover Corporation has become a go-to partner for filters spanning 193 nm to 14 µm-ensuring the performance, durability, and repeatability these systems demand in mission-critical environments. Below, we highlight several optical filter types and how they contribute to the advancing world of laser-based technologies.

Defense & Aerospace: Laser systems are mission-critical for targeting, navigation, surveillance, and threat mitigation. Andover’s optical filters enable safe, precise performance in:

• LiDAR and rangefinding at 1550 nm and 905 nm, with OD4+ blocking outside signal bands for eye safety and improved contrast
• Laser designators and rangefinders using 1064 nm and 532 nm Nd:YAG harmonics
• Dual-band targeting optics, combining MWIR with 1064 nm for integrated imaging and guidance

Our laser-resistant coatings meet strict MIL-SPEC durability and performance standards, providing confidence under extreme operating conditions.

Trend to Watch: Multi-spectral laser integration in UAVs and helmet-mounted displays.

Medical & Life Sciences: Precision is paramount in clinical laser systems, whether for diagnosis, imaging, or treatment. Andover filters are trusted in:

• Fluorescence microscopy, with high transmission at 488 nm, 561 nm, and blocking OD3-OD6 outside the excitation band
• Photodynamic therapy (PDT) using red light in the 630-690 nm range
• Laser-based surgery (e.g., dermatological and ophthalmic) requiring AR-coated optics at 532 nm and 1064 nm

Hard-coated, biocompatible filters offer long-lasting durability in sterilized environments.

Trend to Watch: Surge in deep-tissue NIR laser therapy and diagnostic imaging.

Semiconductors & Microfabrication: Advanced manufacturing relies on laser precision at the smallest scales. Andover provides:

• High LIDT filters for DUV lithography at 193 nm and 248 nm
• Beam delivery optics for 355 nm and 266 nm micromachining
• Wafer inspection filters that enhance signal-to-noise ratios across near-UV and visible ranges

Every filter is custom engineered for wavelength control and thermal stability, essential for repeatable process yields.

Trend to Watch: Demand spike in DUV tools and inline inspection for AI chip production.

Quantum, Communications & Space: As quantum and satellite systems mature, the need for ultra-stable, space-qualified optics grows. Andover solutions support:

• 780 nm and 852 nm filters for rubidium and cesium-based atomic clocks
• 1550 nm telecom filters for quantum key distribution and satellite comms
• 1064 nm filters in optical trapping and cold atom setups

With flight-ready coatings and full-spectrum blocking options, Andover is trusted by institutions advancing the frontiers of space and physics.

Trend to Watch: Push for ultra-stable, miniaturized optical systems on satellites and cube sats.

Precision Manufacturing & Metrology: Laser-based manufacturing demands stable, repeatable optics. Andover delivers:

• OD4-OD6 blocking filters, ND filters, and beam-splitters for welding, cutting, and micromachining
• 633 nm HeNe-compatible optics for metrology and alignment systems
• Angle-insensitive coatings for consistent performance across varied setups

We help industrial innovators improve product quality and process throughput with custom filter solutions.

Trend to Watch: Laser systems with in-line measurement and AI-based quality control.

Laser systems are only as strong as the optical components behind them. Andover Corporation is committed to delivering filters and coatings that meet the technical and operational demands of today’s laser-based technologies. .
