Cf Objectives

  • Lightweight Design with Compact Form Factor
  • Configurable Magnification Using Spacers
  • Optimized For Long Working Distances

TECHSPEC® Cf Objectives are designed to reduce the overall weight and size of an imaging system while maintaining optical performance. While traditional objective systems typically require long tube lengths and tube lenses, TECHSPEC® Cf Objectives optimize each objective to allow for shorter tube lengths. Standardized 30mm outer diameters and C-mount threading ease integration into system assemblies. Magnification can be easily increased by adding spacers to increase the tube length. Each lens has a broadband anti-reflection coating to provide even and maximized light transmission in the visible spectrum. TECHSPEC® Cf Objectives are ideal for a variety of biomedical or machine vision applications including microscopy, flow cytometry, pharmaceutical inspection, and assembly line or fault inspection. Zemax files are available upon request.

Note: A variety of magnifications and numerical aperture options are available upon request to accommodate various resolution, throughput, and depth of field requirements. To ensure a lens is a proper fit for your application, additional contrast, resolution, magnification, and tube length data is available upon request. Please contact technical support to discuss your specific requirements.
