Spectrometer Collimator

Spectrometer Collimator

Spectrometer Collimator

Precision beam collimation from UV to NIR. It delivers stable, parallel optical output for fiber-coupled spectroscopy across an exceptionally broad 200–1500 nm wavelength range.

Designed for researchers and engineers who need reliable fiber-to-free-space coupling without compromising signal integrity. The compact 12 mm focal length and standard SMA905 connector ensure seamless integration with your existing optical setup.

Why FC-12SA-UVN Stands Out

  • Exceptional Bandwidth: 200–1500 nm coverage spans UV photolithography through telecom NIR—one collimator replaces multiple wavelength-specific components
  • Standardized Connectivity: SMA905 interface compatible with major fiber spectrometer brands and accessories
  • Optimized Collimation: 12 mm focal length provides practical working distance for sample interfacing while maintaining beam quality
  • Modular Versatility: Use standalone for free-space coupling or integrate with sample holders, cuvette holders, and filter wheels
  • Rugged Construction: Built for daily laboratory use with stable optical alignment and thermal reliability

Application Solutions

Fiber Spectrometer Coupling

Convert fiber output to collimated free-space beam for cuvette measurements, filter analysis, or sample illumination in UV-Vis-NIR spectroscopy systems.

Material Inspection

Deliver uniform illumination for transmission or reflectance measurements on semiconductors, coatings, and optical components across the full wavelength range.

Research & Development

Flexible beam delivery for experimental setups requiring rapid wavelength switching or multi-wavelength combinatorial studies.

Process Monitoring

Reliable collimation for inline UV curing monitoring, thin-film deposition control, and pharmaceutical coating thickness measurements.

Fluorescence Excitation

Clean beam profile for exciting fluorescence in biological samples, chemical sensors, and quantum dot characterization.

Optical Metrology

Reference beam generation for interferometry, beam profiling, and optical system alignment verification.

Technical Advantages

Broadband Optical Design

  • 200–1500 nm AR coating — Low reflection losses across UV, visible, and near-infrared
  • Chromatic aberration control — Consistent collimation quality from deep UV to telecom bands
  • UV-grade fused silica lens — High transmission at 200 nm without solarization degradation
  • NIR-optimized performance — Maintains beam quality at 1500 nm for telecom and sensing applications

Mechanical Integration

  • SMA905 fiber connector — Industry-standard interface for 200–1100 µm core fibers
  • 12 mm focal length — Practical working distance for sample access and accessory integration
  • Compact barrel design — Fits standard optical mounts and translation stages
  • Locking ring adjustment — Fine-tune collimation without tools, then lock for stability

System Flexibility

  • Standalone operation — Direct fiber-to-beam conversion for custom optical setups
  • Sample holder compatibility — Threads into standard cuvette holders and filter mounts
  • Beam expander option — 12 mm focal length suitable for subsequent beam expansion optics
  • Dual-pass configuration — Can be paired for fiber-to-fiber coupling with sample in between
