LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

The laser optical trapping force can be freely used to capture particles and manipulate their movement
The XYZ three-axis translation stage allows convenient displacement adjustment to achieve relative motion between particles and the laser
By connecting a CMOS camera to a computer, the laser-manipulated particle motion can be displayed in real-time
It can be installed on a 30 cm × 45 cm optical breadboard for easy overall movement without repeated adjustments
A complete set of particle preparation tools, system installation tools, and detailed product manuals are provided for convenient user setup and operation

The basic version of LBTEK's Single-Beam Optical Tweezers System mainly consists of a laser module, dichroic mirror module, CMOS camera module, motion control module, and illumination module: 1) The laser outputs a beam that is incident on the dichroic mirror; 2) The cutoff wavelength of the dichroic mirror is selected to reflect the laser while allowing visible light to pass through. Generally, a short-pass dichroic mirror is chosen, with its cutoff wavelength shorter than the laser wavelength; 3) A high-power oil immersion objective is selected to achieve a finer trapping spot and greater trapping force; 4) The sample is placed on an XYZ three-axis displacement stage, enabling movement along the X, Y, and Z axes; 5) The light emitted by the white LED illumination source is shaped and then directed onto the sample under observation; 6) The illumination light carrying the laser-trapped sample information passes through the objective, transmits through the dichroic mirror, and is reflected by a mirror before being incident on the CMOS camera for imaging; 7) Considering that the dichroic mirror cannot completely block the laser, some of the laser reflected from the sample will partially transmit through the dichroic mirror and reach the CMOS, affecting imaging quality. A filter is added in front of the CMOS to further eliminate the laser beam, and an achromatic lens is used to adjust the field of view while enhancing the brightness of the light incident on the CMOS. LBTEK will soon offer an upgraded standard single-beam optical tweezers system. In addition to all the functions of the basic optical tweezers system, the standard system is equipped with interfaces for connecting expansion modules. It can easily integrate a vortex beam module to drive particle rotation or a fluorescence module for observing the structure and properties of biological cells.

Fixed Microscope Slide Holders

Compatible slides wider than 44 mm
Compatible petri dish diameter: 37.1 mm~41.4 mm
Mounted on a translation mount with M6 tapped holes spaced 50 mm apart

The LBTEK Fixed Microscope Slide Holder is designed for petri dishes and microscope slides on the Z-axis of LBTEK's three-axis translation platform, enabling integration into customized microscope setups such as optical tweezers. Two sets of mounting holes provide versatile applications: one set features four M4 countersunk holes with a 12.5 mm spacing, while the other has two M6 countersunk slots with a 50 mm spacing, ensuring compatibility with various components. The spring clips can be rotated for easy replacement of glass slides and petri dishes. The OT-SH1 clamp features a central 25.4 mm clear aperture for light transmission. The OT-SH35 offers a larger 35 mm clear aperture, accommodating not only microscope slides but also test targets, large-diameter objectives, and other rectangular optical components with widths exceeding 44.0 mm.

Fixed microscope slide holders are commonly used to hold slides, etc.
