The LBTEK Microscope Main Body Bracket With Epi-Illumination Arm is based on a 95 mm optical construction rail, providing long-term stable support and excellent vibration damping. The top of the illumination arm features a female dovetail slot positioned at a 196.5 mm optical path from the rail edge, offering a large working space below, while the bottom has four M3 threaded holes for a 60 mm coaxial system. Additionally, there is a magnetic coupling bellows that creates a light-tight optical path for the objective mount. The length of this bellows can be adjusted within a range of 20 mm to 100 mm. The main body bracket includes a mounting base with M6 countersunk holes, which can be secured to an optical table or breadboard using the included M6 socket head cap screws.

The LBTEK Top Breadboard undergoes an oxidation blackening treatment, allowing system developers to construct custom wide-field observation setups and epi-illumination pathways on the top of an upright microscope. Each breadboard features a Ø38.1 mm through-hole, with the hole center located on the male dovetail block. This dovetail block enables direct connection of the breadboard to the epi-illumination arm of the microscope main body bracket, or can be used to stack breadboards on top of the epi-illumination module. Additionally, there are 8 M3 threaded holes near the Ø38.1 mm through-hole, designed for 30 mm and 60 mm coaxial systems. The purchase includes 4 M4×12 cylindrical head hex socket screws.

The LBTEK Manual Focusing Mount provides a 25.4 mm manual travel range for installed condensers and their mounting brackets. The focusing mount includes a 95 mm dovetail clamp that can attach to the microscope body stand, a manual translation stage, and a mounting bracket with six M3 threaded holes. These six M3 threaded holes are compatible with the M3 countersunk holes on the DMA. When installing the DMA on the manual focusing mount, the optical port aligns with the optical path at a distance of 196.5 mm from the edge of the microscope imaging system rail. The translation stage can be adjusted using the knob. Compared to translation stages with rollers, the manual focusing mount utilizes a dovetail movement mechanism to minimize long-term drift.

The LBTEK Coaxial Arm, when mounted on the microscope main body bracket, can position the optical port at a distance of 196.5 mm from the edge of the vertical guide rail. The coaxial arm provides structural support for user-built optical paths and features a 95 mm dovetail clamp on the back. By tightening two 4 mm hex set screws, it can be secured at any position along the linear dovetail surface of the microscope main body bracket. The CA2 coaxial arm has SM2 female threads and four M3 threaded holes for 60 mm coaxial systems. To offer additional mounting configurations, the four M4×6 socket head cap screws can be removed to separate the 95 mm dovetail clamp from the plate with the optical port. This 12.7 mm thick plate can be connected to a 25.4 mm thick dovetail clamp, aligning the plate's surface with either the top or bottom of the clamp. This flexibility allows the coaxial arm to be installed in the most space-efficient manner while keeping the set screws of the dovetail clamp on the same side as the microscope main body bracket. Included alignment pins ensure proper positioning of the plate relative to the dovetail.

The LBTEK 66 mm Rail Bracket is designed for Ø38 mm dovetail rods with 66 mm dovetail clamps and is compatible with our standard Ø38 mm stainless steel rods. Each bracket includes a locking ring and alignment pin for stable and repeatable positioning. The base can be secured to an optical table or breadboard using M6 socket head cap screws through 4 countersunk holes. Includes 4 M6×16 socket head cap screws.

The LBTEK Solid Stainless Steel Ø38 mm Post comes with a clamping block for 40 mm dovetail rails. This clamping block is secured to the Ø38 mm post using two M6×12 socket head cap screws. The side of the clamping block features a push block designed to hold individual dovetail rails and accessory clamping arms, which can be adjusted and locked using a 3 mm hex key.

The LBTEK Circular Clamping Arm is used for mounting circular slide holders. During use, place the CSS into the Ø110 mm step, then tighten the four clamping plates to secure it. The bottom features a 40 mm dovetail rail, compatible with Ø38 mm dovetail rods. Additionally, the bottom is equipped with M6 threaded holes spaced 25 mm apart, allowing for the installation of other experimental components.

The LBTEK Round Slide Holder is designed for mounting microscope slides in circular clamping arms. The central circular step can accommodate Ø35 mm culture dishes. Featuring a low-profile design, the slide holder reduces the risk of collision with microscope objectives while facilitating easy slide replacement. For custom slide holders of other sizes, please contact Technical Support.

 LBTEK's microscope main body stand without epi-illumination arm is based on a 95 mm optical construction rail, providing long-term stable support and excellent vibration damping. The top area of the microscope main body stand (without epi-illumination arm) offers additional space to support the addition of other DIY compatible modules, making it widely applicable in imaging scenarios. The main body stand includes a mounting base with M6 countersunk holes, which can be fixed to an optical table or breadboard using the included M6 socket head cap screws.

The rail height of this main body stand is 500 mm, and it features the same 95 mm wide linear dovetail mounting surface rail as the microscope main body stand with epi-illumination arm sold by our company.

 The LBTEK mounting platform allows DIY microscopic imaging component modules to be mounted onto the main frame. The mounting platform features an array of M6 threaded holes for installing various optomechanical components.

The snap-in rail bracket can be secured to the main frame by tightening the side M6 screws. When the side M6 screws are loosened, the hinged dovetail clamp can self-open with the assistance of an auxiliary mechanism. As the screws are loosened further, a gap will appear between the dovetail clamp and the main frame, allowing the rail bracket to be installed or removed at any position on the main frame. Alternatively, slightly loosening the side M6 screws enables the rail bracket to slide along the main frame. Tightening the side M6 screws again will secure it at a new position on the main frame.

The rail plate is equipped with an array of 17 M6 threaded holes and 4 M6 countersunk holes. Tightening the four included M6 screws secures the rail plate to the main frame. Beneath these four M6 screws are two T-nut-like components that can be inserted from the end face of the main frame. Therefore, installing the rail plate on the main frame requires the top plate of the main frame to be detachable. For this reason, it is only recommended to install the rail plate on a main frame without an epi-illumination arm. If installed on a main frame with an epi-illumination arm, disassembling the epi-arm may affect the realignment accuracy of the optical path, and such usage is not advised.

Note: If both a rail bracket and a rail plate are installed on the same main frame, the distance between the surface with the array of M6 threaded holes and the main frame will differ by 7.5mm.
