Laser Scanning Confocal Microscope
SIMSCOP P Series Laser Scanning Confocal Microscope

Confocal Microscopy is an optical imaging technique for increasing the Optical Resolution and Contrast of a Micrograph by using a Spatial Pinhole to block out-of-focus light in image formation. Capturing multiple two-dimensional images at different depths in a specimen enables the reconstruction of three-dimensional imaging.

This technology is widely adopted in scientific and industrial, for life science, material, or semiconductor  inspection. However, the cost of the mature commercialized system is usually very high.

SIMTRUM see the needs of the customer to have a robust confocal microscope system with reasonable cost. Our SIMSCOP P Series offers a great balance between functionality, cost, and flexibility.

● Suitable for High-speed and High-SNR imaging

Silicon photomultipliers (SiPMs) consist of an array of SPADs fabricated on a shared substrate, with outputs into a shared readout channel (c). Each element acts as an all-or-none photon detector that produces a pulse of stereotypic height with low variability (d). Pulses from all elements sum to form the SiPM output. A large number of elements in the array (>1000) allows many photons to be detected simultaneously without saturation and enable large active areas compatible with large-etendue objectives.

Upgrade to Fluorescence lifetime imaging microscopy (FLIM) 

FLIM is a type of microscopy that allows for the visualization and analysis of biological samples based on the fluorescence lifetime of the fluorophore being used. FLIM measures the time between the excitation and emission of photons in a sample, which can provide information about the properties of the fluorophore and the environment in which it is located.

FLIM can be used to study a wide range of biological processes, including protein-protein interactions, enzyme activity, and ion concentration changes. It is often used in combination with other imaging techniques, such as confocal microscopy, to provide more detailed information about the sample.

Upgrade to Single / Two /Multi Photon Microscope

In two-photon microscope, a laser emits light at a specific wavelength that is absorbed by the fluorescent molecules in the sample. When two photons of this light are absorbed simultaneously, they provide enough energy to excite the fluorescent molecule and cause it to emit light at a longer wavelength, which can be detected by the microscope. Because two photons are required to excite the molecule, the probability of fluorescence emission is low and only occurs at the focal point of the microscope, allowing for high-resolution imaging and greater depth than conventional microscopes.

Two-photon microscopy has a number of applications in neuroscience, biology, and biomedical imaging. For example, it has been used to study the activity of individual neurons in the brain, visualize the structure and function of blood vessels, and track the behavior of cells in living tissues.

Upgrade to Terahertz Confocal Microscope System

100GHz, output power: 80mW

● Spatial resolution 150-200um

The terahertz confocal microscope uses a focused beam of terahertz radiation to scan the sample being analyzed. This beam is then reflected back and collected by a detector, which creates an image of the sample based on the intensity of the reflected radiation. By using a confocal design, this microscope can achieve high resolution and can selectively focus on different depths within a sample.

 it can be used to study the microstructure and properties of materials, such as polymers, ceramics, and semiconductors, and to detect defects or anomalies in their structures. In biology and medicine, it can be used to image and study biological tissues, including skin, teeth, and cartilage, which are transparent to terahertz radiation.

Upgrade to Super Resolution Confocal Re-scan Structure illumination Microscope

A "re-scan" confocal microscope is a type of confocal microscope that uses a rapidly moving mirror or scanner to scan the laser beam across the sample multiple times, producing even higher resolution and better contrast images than standard confocal microscopes.

Overall, re-scan confocal microscopes are very powerful tools for studying biological tissues, cells, and other samples, and are widely used in research labs, medical facilities, and other scientific settings

Confocal Imaging Applications

Drosophila brain; triple antibody staining:

Alexa 488, Alexa 568 and Alexa 633

Confocal micrograph of Arabidopsis thaliana (thale cress)

Seeding leaf with stomata(yellow moth-like structures)

And parenchyma cells.

Glioblastoma cells in culture transfected with a green fluorescent protein. The nuclei are stained blue with DAPI. The red spots are 0.02-micron fluorescent spheres that have been taken up into the cells by endocytosis. These cells have no endogenous P10 protein; P10 is a tumor suppressor gene that is mutated in many different types of cancer. The absence of the P10 protein is thought to increase cell mobility and possibly contribute to metastasis.

Shown is a confocal microscope image of a human gingival fibroblast in culture. Interphase microtubules (green) are labeled with alpha/beta-tubulin primary antibodies. FITC conjugated secondary antibody was applied afterward. Nuclear DNA (blue) was stained with Hoechst33242.

Live mitotic HeLa cell treated with epsin1 siRNA, DiOC6(3)to label mitotic membranes (green). Confocal images were taken at 0.118 μm steps along the Z-axis.
