Thorlabs offers four families of scientific cameras: Zelux™, Kiralux^®, Quantalux^®, and Scientific CCD. Zelux cameras are designed for general-purpose imaging and provide high imaging performance while maintaining a small footprint. Kiralux cameras have CMOS sensors in monochrome, color, NIR-enhanced, or polarization-sensitive versions and are available in compact, passively cooled housings; the CC505MU camera incorporates a hermetically sealed, TE-cooled housing. The polarization-sensitive Kiralux camera incorporates an integrated micropolarizer array that, when used with our ThorCam™ software package, captures images that illustrate degree of linear polarization, azimuth, and intensity at the pixel level. Our Quantalux monochrome sCMOS cameras feature high dynamic range combined with extremely low read noise for low-light applications. They are available in either a compact, passively cooled housing or a hermetically sealed, TE-cooled housing. We also offer scientific CCD cameras with a variety of features, including versions optimized for operation at UV, visible, or NIR wavelengths; fast-frame-rate cameras; TE-cooled or non-cooled housings; and versions with the sensor face plate removed. The tables below provide a summary of our camera offerings.

Multispectral Imaging

The video to the right is an example of a multispectral image acquisition using a liquid crystal tunable filter (LCTF) in front of a monochrome camera. With a sample slide exposed to broadband light, the LCTF passes narrow bands of light that are transmitted from the sample. The monochromatic images are captured using a monochrome scientific camera, resulting in a datacube – a stack of spectrally separated two-dimensional images which can be used for quantitative analysis, such as finding ratios or thresholds and spectral unmixing.

In the example shown, a mature capsella bursa-pastoris embryo, also known as Shepherd's-Purse, is rapidly scanned across the 420 nm - 730 nm wavelength range using Thorlabs' KURIOS-WB1 Liquid Crystal Tunable Filter. The images are captured using our legacy 1501M-GE Scientific Camera, which is connected, with the liquid crystal filter, to a Cerna^® Series Microscope. The overall system magnification is 10X. The final stacked/recovered image is shown below.

Thrombosis Studies

Thrombosis is the formation of a blood clot within a blood vessel that will impede the flow of blood in the circulatory system. The videos below are from experimental studies on the large-vessel thrombosis in Mice performed by Dr. Brian Cooley at the Medical College of Wisconsin. Three lasers (532 nm, 594 nm, and 650 nm) were expanded and then focused on a microsurgical field of an exposed surgical site in an anesthetized mouse. A custom 1.4 Megapixel Camera with integrated filter wheel were attached to a Leica Microscope to capture the low-light fluorescence emitted from the surgical site. See the videos below with their associated descriptions for further information.

Example Setup for Simultaneous NIR/DIC and Fluorescence Imaging

Live Dual-Channel Imaging

Many life science imaging experiments require a cell sample to be tested and imaged under varying experimental conditions over a significant period of time. One common technique to monitor complex cell dynamics in these experiments uses fluorophores to identify relevant cells within a sample, while simultaneously using NIR or differential interference contrast (DIC) microscopy to probe individual cells. Registering the two microscopy images to monitor changing conditions can be a difficult and frustrating task.

Live overlay imaging allows both images comprising the composite to be updated in real-time versus other methods that use a static image with a real-time overlay. Overlays with static images require frequent updates of the static image due to drift in the system or sample, or due to repositioning of the sample. Live overlay imaging removes that dependency by providing live streaming in both channels.

Using the ThorCam overlay plug-in with the two-way camera microscope mount, users can generate real-time two-channel composite images with live streaming updates from both camera channels, eliminating the need for frequent updates of a static overlay image. This live imaging method is ideal for applications such as calcium ratio imaging and electrophysiology.

Example Images

Simultaneous Fluorescence and DIC Imaging

The image sequence below shows mouse kidney cells imaged using a dichroic filter to separate the fluorescence and DIC signals into different cameras. These images are then combined into a two-channel composite live image with false color fluorescence by the ThorCam overlay plug-in.

Microaspiration Using a Micropipette

The image to the right shows a live, simultaneous overlay of fluorescence and DIC images. The experiment consists of a microaspiration technique using a micropipette to isolate a single neuron that expresses GFP. This neuron can then be used for PCR. This image was taken with our 1.4 Megapixel Cameras and a two-camera mount and shows the live overlay of fluorescence and DIC from the ThorCam plug-in.

Furchgott Center for Neural and Behavioral Science, Department of Pathology, SUNY Downstate Medical Center.

Simultaneous NIR Dodt Contrast and Epi Fluorescence imaging

The image to the right shows a live, simultaneous overlay of fluorescence and near-infrared Dodt contrast images of a 50 µm brain section from a CX3CR1-GFP mouse, which has been immunostained for PECAM-1 with Alexa-687 to highlight vasculature. The Dodt contrast uses a quarter annulus and a diffuser to create a gradient of light across the sample that can reveal the structure of thick samples. The image was taken with our Scientific Cameras and a two-camera mount.
