TLV-U-MF2 Thorlabs Cube for Olympus MDFM-QFXL OEM Cube for Nikon E200-1000 and TE200 Microscopes TLV-TE2000 Thorlabs Cube for Nikon TE2000 and Eclipse Ti Microscopes Application Idea Thorlabs' TLV-TE2000 Filter Cube Related Items ![]() Please Wait ![]() Click to Enlarge Thorlabs’ filter cubes (top) retain the dichroic beamsplitter using a spring plate that applies force evenly, putting less stress on the optic compared to OEM cubes (bottom). The spring plate is also premounted on the cube, simplifying the assembly process. ![]() Click to Enlarge Thorlabs' filter cubes feature labels for identifying installed filters. Features
We offer Thorlabs and OEM Drop-In Filter Cubes for select Cerna, Olympus, and Nikon fluorescence microscopes. Each filter cube holds one Fluorescence Filter Set, which includes an excitation filter, emission filter, and dichroic mirror/beamsplitter. Optics can be mounted, aligned, and swapped out easily, following the videos and assembly instructions below. Please see the compatibility tables below to determine the correct filter cube for your application. Compared to OEM filter cubes, Thorlabs' filter cube design features improved dichroic mirror retention for lower optic distortion, simplified optic mounting (see photo to the right), and three engraved labels for writing information about installed filters (see photo above). These drop-in filter cubes are offered as empty mounts. The filter cubes are compatible with excitation filters (Ø25 mm, up to 5 mm thick), emission filters (Ø25 mm, up to 3.5 mm thick), and dichroic mirrors (maximum sizes vary, please see below for details) which are commonly used in applications targeting specific fluorophores. Select filter sets are available pre-installed into Thorlabs' filter cubes here. For other filters and custom requests, please contact Technical Support. Note: Thorlabs does not guarantee compatibility with other industry-standard microscopes not mentioned on this webpage.

Thorlabs' filter cubes feature a spring plate retention mechanism for the dichroic mirror that results in lower optic stress for improved imaging. Our design also offers an all-aluminum cube body, simplified optic mounting, and three labels for writing information about installed filters. Each cube is also engraved with the item number. Refer to the table below to view which filter cubes are compatible with which microscope. These cubes are also available with pre-installed imaging filter sets. Each filter cube holds one set of fluorescence filters: an excitation filter, an emission filter, and a dichroic mirror; see table below for compatible sizes. Optics can be mounted, aligned, and swapped out easily as illustrated in the video to the right. For detailed assembly instructions, please refer to the assembly manuals in the table below. The excitation and emission filters are mounted using the included SM1RR Retaining Rings and an SM1 spanner wrench, such as the SPW606 (sold separately). The use of SM1RR retaining rings across all filter cubes makes it easier to replace lost or damaged rings. The filter cube bodies may be disassembled for optic installation or removal using a #1 Phillips screwdriver. Note that the OEM filter cubes sold below utilize plastic in their construction, while these filter cubes have aluminum bodies. When mixed in a filter cube turret, it is important to balance the weight. To ensure longevity of a motorized filter cube turret and prevent unnecessary wear, please place matching filter cubes opposing each other to maintain balance.
Please contact Tech Support with questions regarding other cube compatibility, mounting, and filter options. Thorlabs does not guarantee compatibility with other industry-standard microscopes not mentioned on this wepage. ![]() Installation of Filters into the MDFM-MF2 Cube
These OEM Filter Cubes are manufactured by Olympus and Nikon. Each filter cube holds one set of fluorescence filters: an excitation filter (Ø25 mm, up to 5 mm thick), an emission filter (Ø25 mm, up to 3.5 mm thick), and a dichroic mirror (up to 25.2 mm x 36.0 mm x 1.0 mm). Optics can be mounted, aligned, and swapped out easily as illustrated in the video to the right. Each filter cube body may be disassembled for optic installation or removal using a Phillips head screwdriver. For detailed assembly instructions, please refer to the assembly manuals in the table below. Thorlabs' Filter Cubes (sold above) are interchangeable with these OEM cubes and offer a number of design improvements, including simplified mounting and reduced dichroic mirror stress for improved imaging. Note that these OEM filter cubes utilize plastic in their construction, while Thorlabs' filter cubes (sold above) have aluminum bodies. When mixed in a filter cube turret, it is important to balance the weight. To ensure longevity of a motorized filter cube turret and prevent unnecessary wear, please place matching filter cubes opposing each other to maintain balance.
