The LBTEK single objective mounting bracket allows for the installation of a single objective lens in the optical path at a distance of 196.59 mm from the main support structure. It is designed to directly accommodate objective lenses with an M32 x 0.75 external thread. Alternatively, our microscope adapters can be used to convert the M32 x 0.75 thread to other industry-standard objective lens threads, such as M26 x 0.706, RMS thread, and others.

With a thickness of only 9.5 mm, the mounting bracket maximizes available space in the Z-direction, facilitating the installation of other microscope modules. It features four M3 threaded holes compatible with a 60 mm coaxial system. Additionally, six M4 countersunk holes on the bracket enable easy mounting onto manual focusing stages (sold separately by our company). The magnet on the upper part of the bracket is used to attach the light-blocking bellows to the main support structure with an epi-illumination arm, creating a light-tight optical path between the bracket and the epi-illumination arm to prevent interference from external light.

LBTEK Adjustable Mount can install a single objective lens in the optical path at a distance of 196.59 mm from the main bracket. The mount consists of one mounting arm and one detachable magnetic objective lens mount, allowing users to quickly switch objective lenses without disassembling the entire mount. The ball + V-groove design on the mounting arm and the detachable magnetic objective lens mount provides dynamic positioning functionality, enabling sliding in and out for quick replacement of the objective lens mount, with a repeat positioning accuracy of < ±10 µm in the X and Y axes. The mount has a thickness of only 12.7 mm, maximizing space in the Z-direction to facilitate the installation of other microscopy modules. Four M3 threaded holes are compatible with a 60 mm coaxial system. Six M4 countersunk holes on the mount allow for easy installation onto a manual focusing mount (sold separately by our company).

The detachable magnetic objective lens mount (SOFA-A) can directly accommodate objective lenses with an M32 x 0.75 external thread. Alternatively, our company's microscope adapters can be used to convert the M32 x 0.75 thread to other industry-standard objective lens threads, such as M26X0.706, RMS thread, etc. Four M3 threaded holes on the mount allow for the construction of a detachable 60 mm coaxial assembly. The magnet on the upper part of the mount is used to attach the light-blocking bellows on the main bracket with an epi-illumination arm, forming a light-tight optical path between the mount and the epi-illumination arm to prevent interference from external light.

The objective lens mounting frame allows for the installation of five objective lenses in a self-assembled microscopic system, facilitating the construction of systems that require switching between multiple high and low magnification objective lenses. The housing and threads of the objective lens mounting frame are made of copper, with a stainless steel backplate at the top. The combination of a spring plate and a hard stainless steel ball, along with the positioning grooves on the housing, forms a precise positioning mechanism. This positioning mechanism can secure the objective lens, ensuring an objective lens switching positioning accuracy of ≤±50 μm and a single-hole bidirectional repeatability of ≤30 μm. It ensures that the optical components in the system are aligned with the optical axis both vertically and horizontally. The five objective lens mounting threads at the lower end of the FOF1 are RMS threads. The upper end of the objective lens mounting frame features a D1T male dovetail, which can be mounted onto a manual focusing stage using a DMAS mounting arm (sold separately).

The LBTEK Dual-Objective Nosepiece is constructed from 6061-T6 aluminum alloy for high precision and excellent rigidity. It features two M32 x 0.75 threaded holes with a center distance of 63.5 mm, accommodating objectives of varying magnifications. For objectives with other thread sizes, LBTEK thread adapters are available, or you may contact technical support for custom installations.

LBTEK mounting arm, used to install the objective lens mount onto a manual focusing stage. The objective lens mounting hole on the arm features a φ38.2 mm female dovetail, compatible with five-objective lens mounts, dual-objective lens mounts, and single-objective lens mounts (requires a dovetail adapter for use). The magnet on the upper part of the mounting arm is used to attach the light-blocking bellows on the main bracket with epi-illumination arm, forming a light-tight optical path between the mounting arm and the epi-illumination arm to prevent interference from external light.

LBTEK objective adapters include threaded adapters with internal and external thread specifications such as M26×0.706 and M32×0.75 threads. The surface is black anodized to reduce stray light reflection. LBTEK continuously introduces new adapters; please refer to the technical specifications. In addition to standard threaded adapters, LBTEK also offers custom adapter services for special-sized thread specifications. If needed, please contact LBTEK technical support.
