Custom microscope objective lens design, development and series production

Our customer required a custom microscope objective lens optimized for operation in wavelength of 405nm. Our optical engineers reviewed the initial requirements and the information regarding the function of the overall system and, together with the customer, they set the final specifications (parameters and values).

ASE Optics realized a preliminary design based on our internal existing knowledge base in optical design for custom microscope objectives development and manufacturing and taking into account the desired specifications and requirements given by the customer. After several iterations, ASE Optics provided a preliminary design, that met the requirements in nominal design.

Some of the main specifications were:

  • NA 0.5
  • EFL 3.6 mm
  • Total length 19 mm
  • Telecentricity
  • Entrance Pupil Position: 3.56 mm from first vertex
  • Back focal plane: 4.01 mm from first vertex

ASE Optics also evaluated the as-built performance at 405nm, to give customer a realistic performance data. We suggested to customer to consider some modifications in some values, to make the microscope objective cost-effective for a series production. The customer accepted these modifications, as they did not affect the quality of the system, happy to notice that ASE Optics could balance all the important aspects: quality, technical and optical performance, costs, lead times and manufacturability.

Scope of work and technical details

Our optical engineers designed and developed a robust system that performs to nearly diffraction limited over the full-field, always with series production in mind. The system was to assure durability in operation compatible with 405nm illumination. And LIDT requirements were taken into account, to obtain a lens compatible with this requirement as well.
