LINOS Precision Optics, Machine Vision Lenses, and Laser Photonics Components

LINOS d.fine HR, inspec.x, MeVis-C, and Rodagon Machine Vision Lenses

High-resolution industrial imaging lenses from LINOS spanning the d.fine HR series (engineered for line-scan and area-scan sensors up to 150 MP with 2.4 µm pixel pitch and a 57 mm image circle), inspec.x L and inspec.x M (large-format metrology objectives covering sensor diagonals up to 82 mm), fast

MeVis-C lenses (f/1.4–f/1.8 C-mount industrial optics), and legendary Rodagon and Apo-Rodagon-N reproduction lenses deliver diffraction-limited optical performance across the full field.

Precision apochromatic correction eliminates axial and lateral chromatic aberrations, ensuring high modulation transfer function (MTF) contrast for sub-micron defect detection on automated PCB inspection, flat-panel OLED/LCD verification, and semiconductor wafer metrology lines.

Flat-field scanning lenses from the LINOS F-Theta-Ronar portfolio (covering UV 355 nm, green 532 nm, near-infrared fiber and disk lasers at 1030–1080 nm, and CO2 wavelengths at 10.6 µm) in standard and telecentric configurations are engineered for high-speed galvanometer scanner heads.

Manufactured from ultra-pure synthetic fused silica and specialized optical glasses using cement-free air-spaced mounts and low-absorption AR coatings, these objectives withstand extreme peak power densities from ultrashort pico- and femtosecond lasers as well as multi-kilowatt continuous-wave (CW)

beams in EV battery welding, selective laser melting (SLM/LPBF) additive manufacturing, and micro-structuring.

• Low-absorption fused silica optics: minimal thermal focus shift under multi-kilowatt continuous-wave laser irradiation

• Wavelength-specific AR coatings: optimized for 355 nm, 532 nm, and 1030–1080 nm with high laser-induced damage thresholds
• Exchangeable protective windows: quick-release fused silica cover slides shielding internal lens elements from weld spatter

LINOS FI and DLI Magneto-Optic Faraday Isolators and Polarization Rotators

Magneto-optic Faraday isolators (optical diodes) from LINOS across the FI-305, FI-500, FI-780, FI-1064 series, alongside dual-stage DLI high-isolation assemblies and broadband tunable isolators for Ti:Sapphire lasers, safeguard laser cavities, seed diodes, and frequency-stabilized oscillators

against destabilizing back-reflections.

Engineered with high-purity Terbium Gallium Garnet (TGG) crystals and specialized magneto-optic glasses housed inside field-compensated neodymium magnet assemblies, these isolators achieve forward transmission up to 95–98% and reverse optical isolation from 30–35 dB (single-stage) up to >60 dB

(dual-stage DLI) across wavelengths from 320 nm to 1650 nm.

• Spectral coverage from 320 nm to 1650 nm: dedicated models for UV, visible, diode, Ti:Sapphire, and 1064 nm lasers

LINOS Pockels Cells and Electro-Optic Modulators BBPC, CPC, and LM Series

Electro-optic modulators (EOM) and Pockels cells from LINOS—including the BBPC series utilizing Beta-Barium Borate (BBO) crystals, CPC and DPC series based on deuterated potassium dihydrogen phosphate (KD*P), and low-voltage transverse modulators LM 0202 and LM 13 on ADP and RTP crystals—deliver

nanosecond-speed control over laser polarization, phase, and amplitude.

BBPC and CPC Pockels cells serve as high-contrast Q-switches, pulse pickers, and cavity dumpers inside regenerative ultrafast laser amplifiers, while LM 0202 modulators provide broadband intensity stabilization, laser noise suppression, and Pound-Drever-Hall (PDH) frequency locking.

LINOS Fixed and Motorized Variable Zoom Laser Beam Expanders

Galilean laser beam expanders from LINOS—available in fixed magnification ratios (from 2x to 40x) and pancratic variable zoom configurations (1x–4x, 2x–8x in manual and motorized versions)—are engineered for precise adjustment of beam diameter and divergence prior to galvanometer scanners and

focusing objectives.

Cement-free optical assemblies utilizing synthetic fused silica and low-absorption optical glasses prevent thermal degradation under high-power laser loads, maintaining diffraction-limited wavefront quality (wavefront distortion < λ/4) across 266 nm, 355 nm, 532 nm, and 1030–1080 nm laser
