Designs shared on this site are offered under one of two specific terms-of-use agreements. See specific terms posted next to download areas for each separate microscope system.


Users of these designs must register first before designs will be made available. Registration forms are available in the pages for each separate microscope system.

Design format

Parts list

Parts lists in MS Excel format are available.

Mechanical designs

Mechanical designs of individual parts designed at JFRC and CSHL are available as PDF files of production drawings, suitable for sending to most machine shops. Full 3D assemblies of parts are available as Design Web Format (DWF) files, which can be viewed using the free Autodesk Design Review software. The DWF assembly files contain all parts in the main assemblies, including commercial-off-the-shelf (COTS) items, and contains basic information about each part (including part number, and vendor and estimated price for COTS items). Autodesk Design Review supports taking measurements on any parts in the assembly.

Electrical designs

A few custom-made electrical components are used with these designs at JFRC. Schematic and/or PDF Gerber files are available so that these may be reproduced.

Optical designs

Optical designs (placement and separation of lenses, mirrors, filters, etc.) will be present in the mechanical assembly files to an accuracy sufficient for microscope assembly. Detailed optical designs of COTS and custom-ordered compound lenses are not owned or shared by JFRC. Optical designs in ray-trace modeling programs OSLO and TracePro may be available upon request.


All designs have been used exclusively with the open-source ScanImage laser scanning microscope software.

Design "philosophy"

The microscope systems with shared designs on these pages are not turn-key systems. The designs were not necessarily created to maximize ease of assembly, and ease of use once assembled will usually not match that of turn-key systems.

Designs were usually created with the intent to make future customization, modifications, and experimentation relatively easy. Assemblies are generally open, and will often contain more degrees of freedom than would be expected with a monolithic, turn-key system, to allow the system to work with many different key components (lenses, scan systems, etc). Use of well-stocked, commercially available parts is made were possible. However, useless degrees of freedom which would result from exclusively COTS (e.g. Thorlabs) construction, and would require unnecessarily difficult assembly procedures, were usually eliminated through the use of custom parts.

titleExperience required

Considerable effort and some skill will be required to successfully assemble these microscopes. Exhaustive documentation, necessary for a novice in custom mechanical construction and laser optics setup/alignment, do not exist. Experience in laser optics and alignment, and detailed knowledge of physical principle of TPLSM will be necessary.

titleLaser safety

Designs were not created to comply with any laser safely guidelines. Users are responsible for ensuring that they and others will not be exposed to dangerous laser radiation. Uncontrolled laser beams will be produced by these open-architecture microscope systems unless care is taken to block them!

Non-MIMMS In Vivo


Image Removed


The MIMMS and non-MIMMS systems use more-or-less the same non-descanned detection optics and can use the same scan mirrors, so will have similar performance for basic operation. The non-MIMMS in vivo microscope systems, in contrast to the MIMMS system:

  • provides for only three degrees of freedom of objective movement (no rotation of objective is possible),
  • uses no mechanical parts from any microscope manufacturer, and will probably have a lower total cost of purchased parts,
  • uses an Olympus trinoc assembly, allowing for visual observation mode,
  • has extensive documentation for assembly, provided by Anthony Holtmaat,
  • will have a more-incomplete parts list and set of mechanical designs, due to lack of recent design efforts at JFRC (experience in custom 2P microscope construction will be necessary to "fill in the blanks").
