• This dovetail designation is specific to Thorlabs products; see the Microscope Dovetails tab for details.
• For 60 mm cage compatibility, add the LCP11(/M) cage plate (sold separately). The CP38T can be used for 30 mm cage compatibility, but will reduce the clear aperture.

Use the SM2Y1 epi-fluorescence port adapter with the LCP11(/M) cage plate to attach 60 mm cage systems.

The SM2Y1 port adapter connects to the epi-fluorescence port on certain Olympus IX71 microscopes. The image to the right shows what an epi-fluorescence port of an Olympus IX71 microscope should look like for the SM2Y1 to be compatible. If the microscope does not appear as pictured, then the port adapter will not work. If you are unsure about compatibility, please contact Tech Support.

The SM2Y1 features internal SM2 threading on one side and internal SM30 threading on the other, allowing it be integrated into an externally SM2-threaded illumination source or Ø30 mm optic. One SM2RR retaining ring is provided with the SM2Y1 and can be used to secure a Ø2" optic up to 1.10" (28.0 mm) thick against the internal lip of the adapter; thicker retaining rings (Item # SM2RRC) are available for high-curvature lenses, though the curvature will limit the usable mounting depth. Please contact Tech Support to ensure a proper fit. The other side of the adapter can be used for Ø30 mm optics up to 1.09" (27.7 mm) thick using two SM30RR retaining rings, which are available for purchase separately.

Please note that the SM2Y1 adapter can be paired with the LCP11(/M) cage plate for 60 mm cage system compatibility. First attach the LCP11(/M) to the SM2 threads of the SM2Y1, then secure the connected adapters to the epi-fluorescence port by way of the circular dovetail on the SM2Y1 (see image to the right for alignment details). For 30 mm cage compatibility, consider using the CP38T cage plate; note that the cage plate will reduce the clear aperture.

Note: Thorlabs does not guarantee compatibility with other industry-standard microscopes not explicitly mentioned on this webpage.

Connecting the LCPY1(/M) to the Transmitted Illumination Port

These transmitted illumination port adapters provide compatibility for the Olympus BX41, BX51, IX71, IX73, IX81, and IX83 series microscopes with a range of Thorlabs' optomechanical products. The SM1A14B, SM2A7B, LED4A1, and SM2A13 adapters fit inside the trans-illumination port, while the LCPY1(/M) sits flush against the port. Two SM2RR retaining rings are provided with the LCPY1(/M) and can be used to secure Ø2" optics up to 1.24" (31.6 mm) thick within the optical path; other retaining rings are available for purchase separately, including thicker retaining rings for high-curvature lenses. The LCPY1/M features a small dimple indicating it is a metric part.

Cage Compatibility	30 mm Cage (4-40 Through Tap, 4 Places)
Microscope Compatibility	Olympus BX and IX Camera Ports

The SM1A51 is designed so that custom-built optical systems or detectors based on Thorlabs' components may be attached to the camera port of Olympus BX or IX Microscopes.

The SM1A51 features internal SM1 threading for Ø1" Lens Tubes and 4-40 tapped through holes on 30 mm centers for attaching cage rods. Our Scientific Cameras with internal C-mount threads can be adapted to SM1 threading using a C-Mount to SM1 adapter (Item # SM1A39), available separately. To achieve proper parfocality, we recommend using a Ø1" lens tube with 3" thread depth (Item # SM1L30) with the Olympus BX or IX microscopes and camera port adapters. In addition, an SM1-threaded dust cover (Item # SM1CP2) is included to keep the port closed when not in use.

LCPY2 Adapter Attached to Exposed Trinocular Port

The LCPY2 Trinocular Port Adapter allows custom widefield viewing setups to attach to an Olympus IX or BX Microscope. This adapter utilizes a male D5Y dovetail adapter to connect to the trinocular port of the microscope; see the Microscope Dovetails tab for details. This adapter can only be attached by first removing the microscope's trinoculars (see image to the right).

This adapter features internal SM30 threading for Ø30 mm lens tubes; two SM30RR retaining rings are included to secure an optic inside the adapter. Through holes with side-located locking 8-32 setscrews (5/64" [2 mm] hex) can be used to attach Ø6 mm cage rods for 60 mm cage systems. The side opposite the dovetail has 4-40 tapped holes on 30 mm centers for compatibility with 30 mm cage systems.

• Additional information on dovetails is available in the Microscope Dovetails tab.
• The LCPN3 adapter features an additional male D1N dovetail to connect to the trinocular port of a Nikon Eclipse (Upright, Ti, and Ti2) or Cerna microscope.

Thorlabs offers two adapters that interface with Olympus trinoculars to incorporate them into custom microscope systems. The LCPN3 and LCPY3 Trinocular Adapters utilize a female D5Y dovetail to connect to an Olympus trinocular via a side-located M4 x 0.7 setscrew (5/64" [2 mm] hex). Please note that the trinoculars must be detached from the microscope itself prior to mounting these adapters.

The LCPN3 adapter features internal SM30 (M30.5 x 0.5) threading for Ø30 mm lens tubes, providing a clear aperture of Ø1.10" (Ø27.9 mm); two SM30RR retaining rings are included to secure an optic inside the adapter. A male D1N dovetail is included on the side opposite the female D5Y dovetail, allowing for integration with the trinocular port on an Upright Nikon Eclipse, Nikon Eclipse Ti, Nikon Eclipse Ti2, or Cerna Microscope. Four through holes, each with two side-located locking setscrews (5/64" [2 mm] hex), can be used to attach Ø6 mm cage rods for 60 mm cage systems.

The LCPY3 adapter is unthreaded with a clear aperture of Ø1.26" (32.0 mm). It features four through holes with side-located locking M4 x 0.7 setscrews (5/64" [2 mm] hex) that can be used to connect 60 mm cage systems and integrate into Cerna microscope systems. Additionally, the side opposite the dovetail has 4-40 tapped holes on 30 mm centers for compatibility with 30 mm cage systems.

Two SM2Y2 adapters replace the lens elements of the trinocular eyepieces.

The SM2Y2 Eyepiece Port Adapter allows custom-built optical detection systems to attach to the eyepieces on the trinoculars of an Olympus IX or BX Microscope. This adapter replaces the lens element on the eyepiece that sets the image plane focus at the the back of the eyes (see image to the right). Because of the drop-in nature of the adapter, take care the attached system does not overbalance the 40 g eyepiece adapter when it is inside the trinoculars. Thorlabs recommends no more than 0.5 lbs at a distance of 5" from the adapter; the maximum torque to avoid rotation is 16.96 N•mm.

This adapter features 1.19" (30.2 mm) of internal SM1 threading for Ø1" lens tubes or optics, external SM2 threading for Ø2" lens tubes, and 4-40 tapped through holes on 30 mm centers for compatibility with a 30 mm cage system. The adapter includes two 0.08” thick SM1RR retaining rings to secure an optic inside the adapter.

SM2Y3 Adapter Attached to Condenser Holder of Olympus IX71

Click to Enlarge
The back of the SM2Y3 adapter has internal SM2 threads and 4-40 taps for 30 mm cage compatibility.

The SM2Y3 Condenser Port Adapter allows custom condenser configurations to attach to an Olympus IX or BX Microscope. The adapter utilizes a male D4Y dovetail to connect to the condenser holder of the microscope; see the Microscope Dovetails tab for details.

This adapter features internal and external SM2 threads for Ø2" lens tubes, achromatic doublets, or other optics as well as 4-40 tapped through holes on 30 mm centers for compatibility with a 30 mm cage system. One SM2RR retaining ring is included to secure a flat or mounted optic against the internal lip of the adapter, such as a filter or iris. The adapter lip limits the clear aperture to Ø1.5".
