3 Camera Overview Quantalux scmos Cameras Thorlabs 2.1 Megapixel Quantalux scmos cameras are based on highperformance, 1 e - read noise imagers. Ideal for demanding applications, the monochrome sensor (color available late 17) can image the full 19 x 8 frame at 5 fps with 16 bit resolution and offer a peak quantum efficiency of 61% at 6 nm. Packaged in a housing that measures 2.38" x 2.78", each scmos camera is equipped with passive thermal management, reducing dark current without the need for a cooling fan or thermoelectric cooler. A USB 3. interface provides compatibility with most computers. The compact housing is feature-rich, enabling seamless integration into a multitude of setups. An adjustable C-Mount adapter is factory installed into the SM1-threaded optical aperture of the camera for out-of-the-box compatibility with industry-standard microscopes and camera lenses. Various mounting taps are also provided for optical post and 3 mm cage system compatibility. Scientific-Grade CCD Cameras Thorlabs scientific CCD cameras are offered in two package styles: a noncooled package and a hermetically sealed package with a two-stage TEC. The fan-free cooler design provides optimal CCD cooling without vibration, critical for capturing long-exposure images in low-light conditions. Each CCD camera is available with either a USB 3., Gigabit Ethernet (GigE), or Camera Link interface. GigE is ideal when the camera must be far from the PC or when there are multiple cameras that need to be controlled by the same PC. The USB 3. and Camera Link interfaces offer higher maximum data transfer rates. CCD cameras feature standard C-Mount threading, and Thorlabs provides a full line of thread-to-thread adapters for compatibility with other thread standards. The front face is also equipped with 4- tapped holes for compatibility with our 6 mm cage system. Four 1/4"- tapped holes, one on each side of the housing, are compatible with our Ø1" Posts. These features make Thorlabs cameras an ideal choice of CCD imager for both DIY and commercial imaging systems for microscopy. Quantalux scmos Camera Hermetically Sealed, Cooled CCD Camera Non-Cooled CCD Camera Our Quantalux scmos Cameras can be integrated into our 3 mm cage system to construct custom imaging systems. Scientific CCD cameras can be integrated into our 6 mm cage system. A C-Mount lens mount allows integration with our family of machine vision camera lenses. Thorlabs thread adapters and lens tubes can be used to create unique solutions. Here, a scientific CCD camera is integrated with our our SM1 lens tubes and Cerna modular microscopy platform for custom epi-fluorescence imaging.

4 Images from Selected Applications Intracellular Dynamics Fast Frame Rate Cameras can be used for Ca 2+ ratiometric studies of intracellular dynamics. Highspeed imaging is made possible by the fast frame rate of the camera as two excitation wavelengths are switched in rapid succession. Alternately, quantitative imaging data can be acquired from fluorescence emission at two distinct wavelengths. Brightfield Microscopy A brightfield microscopy image showing Ki-67 labeled tonsil cells. Ki-67 is an antigen that only appears in the nuclei of cells undergoing division; therefore, it is an excellent marker to indicate the growth fraction of a cell population. u Quantalux TM scmos u Fast Frame Rate, VGA u High QE u Low Noise u ROI and Binning Modes u 4 Megapixel u 8 Megapixel u High Resolution u Large Field of View Ophthalmology (NIR) Retinal/fundus imaging in the NIR to view the blood vessels in the eye. u Quantalux TM scmos u NIR Responsivity u Low Noise Neuroscience Fluorescence image of a rat neuron using X magnification. u Quantalux TM scmos u High QE u Low Noise u Thermal Management

The Dodt contrast uses a quarter annulus and a diffuser to create a gradient of light across the sample that can reveal the structures of thick samples.

6 Quantalux TM scmos Cameras Our Quantalux scmos cameras are the ideal camera for applications such as fluorescence microscopy due to their low read noise and high dynamic range. Below is an analysis of how these superior specifications lead to better images, and thus better quantitative results, at low light levels. High Sensitivity with <1 e - Read Noise Quantalux scmos cameras have significantly lower read noise, with comparable quantum efficiency, when compared to the CCD sensors used in more conventional scientific cameras. The relative impact of read noise on quantitative measurements will depend upon its contribution to the total noise, relative to the signal-dependent photon shot noise. A measure of camera performance under different noise levels is the Signal-to-Noise Ratio (SNR). The plot below and to the left shows the SNR for our Quantalux camera, a typical conventional CCD camera, and an ideal, shot-noise-limited detector (with no read noise and % quantum efficiency). The plot below and to the right shows the same results normalized to the SNR of an ideal detector under the same conditions. As can be seen in the plots, our Quantalux camera produces images with higher SNR at lower photon levels. Quantalux cameras can be expected to yield higher SNR images than a conventional CCD camera under conditions in which only approximately to photons/pixel are expected to be captured in a given exposure. The specifications of Quantalux cameras make them an ideal choice for a wide range of fluorescence microscope imaging needs and other low-light applications.

7 High 87 db Dynamic Range for Capturing Dim Details and Bright Features A common problem in fluorescence microscopy involves imaging bright fluorescent features in the presence of a dim background. If the camera doesn t have a large enough dynamic range, saturation and floor limitations will limit the simultaneous capture of both bright and dim features. With the Quantalux camera s high dynamic range of 87 db, a single exposure gathers sufficient contrast of bright, moderate, and dim objects at once. The images below show how a single high dynamic range image can be analyzed and visualized to highlight features over any one of these brightness ranges. Figure 1: The Contrast Dialog Window. These settings were adjusted to process the images shown in Figures 2 through 3c. The Contrast settings can also be adjusted during live imaging. Figure 3a: The image contrast from Figure 2 has been adjusted to highlight the amyloid plaque core details. The background, including fibrils and cells, is hidden from view. Figure 3b: The contrast from Figure 2 has been adjusted to highlight the fibrils in the sample, resulting in saturation of the plaque core details in the original image. Figure 2: ThorCam screenshot of an unprocessed image taken using our monochrome Quantalux scmos camera. The sample is a ~ μm thick slice of 5xFAD mouse with amyloid plaques stained with Thioflavin S. The image was acquired at 65 ms exposure using a X,.75 NA immersion objective with water, corrected for the #1.5 coverslip used. Images are courtesy of Craig Brideau, University of Calgary, Alberta, Canada. Figure 3c: Maximizing the background contrast shows nearby cell bodies and nuclei for cytometry; however, the contrast adjustment saturates both fibrils and the plaque cores.
