Optics Engineering

A dedicated, on-site optical lab lets us provide clients with rapid, robust breadboard development and designs that translate into reliable prototype and production instruments. Our finely-tuned, state-of-the art optics R&D pipeline bridges back-of-the-envelope calculations to full production solutions. The vast experience of our multidisciplinary optics team ranges anywhere from multi-wavelength flow cytometry to fluorescence imaging to high- and low-power digital microscopy.

Optical engineering capabilities:

  • Theoretical design and modeling
  • Rapid breadboard feasibility analysis and testing
  • Custom imaging and non-imaging detection systems
  • Custom illumination systems
  • Custom light pipe design
  • Fluorescence and polarization-based epi-illumination systems
  • On-the-fly data acquisition and analysis
  • High volume, low cost systems
  • Low volume, custom engineered solutions
  • Single and multi-mode fiber optic systems
  • F-Theta scanning systems
  • High speed, high magnification scanning imaging systems

Recent projects:

  • Scanning F-Theta detection system with integrated, scanning MEMS mirror
  • Visual alignment system for opaque samples designed for up to 90% obscuration of the clear aperture, and user selectable specular or scattered reflection detection
  • Tissue proximity sensor
  • LED illuminator for fluorescence detection
  • High speed, high magnification scanning imaging systems ranging from custom lab-on-a-chip fluorescent nanosphere detection to standard microscope slide imaging of clinically prepared tissue
  • Custom light-pipe
