Hamamatsu Photonics K.K. Introduces W-VIEW GEMINI-2C Camera
Sep 22 16
Hamamatsu Photonics K.K. has introduced the W-VIEW GEMINI-2C camera. This is a dual camera, dual channel system engineered with super resolution quality, while simultaneously offering versatility, expandability and ease of use. The W-VIEW GEMINI-2C turns a simple optical concept into an elegant and useful tool that can help maximize the information content of every image acquisition. Using custom designed optics, engineers fully optimized system performance, offering super resolution quality by minimizing point spread function (PSF) degradation, field curvature and wave front aberration. Maintaining optical quality at the edges of the field demands extra care. The W-VIEW GEMINI-2C delivers excellent performance over the entire fi eld of two ORCA-Flash4.0 sreries cameras and diffraction-limited performance within the center 12 mm diameter FOV. This unmatched level of optical performance delivers bright, even, chromatic aberration-corrected images to both cameras. The W-VIEW GEMINI-2C makes alignment easy and stable. Included alignment software provides direct visual feedback when using Hamamatsu cameras. An optional grid chart fits directly into the primary imaging plane making it possible to align images in the absence of feedback at the sample position. All filter and beamsplitter holders are designed to industry standard specifications, allowing researchers to freely choose their optical components. It's easy to bypass all the optics of the W-VIEW GEMINI-2C, simply remove the filters and beamsplitter and insert the port covers. In addition, by using a 100% mirror instead of a beamsplitter, the W-VIEW GEMINI-2C can be used to switch between two different cameras. With input and output C-mounts, the W-VIEW GEMINI-2C is compatible with and easily attached to standard inverted microscopes. Existing dual camera, dual wavelength imaging devices use two commercially available doublet lenses. Optical modeling shows large field curvature and astigmatism in the existing doublet lens design, making it impossible to employ these lenses for super resolution applications. To overcome this optical limitation, the W-VIEW GEMINI-2C uses custom designed and manufactured lenses that minimize wavefront aberrations to maintain the diffraction limit. The W-VIEW GEMINI-2C was specifically developed to bring the temporal advantage of simultaneous dual channel imaging to cutting edge applications. To faithfully reproduce sample position, intensity and distribution characteristics across two sCMOS cameras requires refined optics. Using simulations of a spot projected through the optical system, the resolution of the W-VIEW GEMINI-2C, as shown by the size and shape of the beam at 0, 3 and 6 mm from optical center, is significantly better. This data is shown for both high magnification, typical for single molecule and super resolution experiments, and low magnification, typical for lightsheet imaging systems. The 4f configuration of the optics makes it possible to connect multiple W-VIEW GEMINI-2Cs for full-field, tri-color, threecamera imaging. Alternatively, the addition of two single camera W-VIEW GEMINI devices provides quad channels imaged onto two ORCA-Flash4.0 series cameras. The W-VIEW GEMINI-2C is the first dual channel imaging device supporting engineered point spread function (PSF) imaging. For example, by using phase masks, to create known modifications to the PSF, additional z position information can be extracted from a single plane permitting rapid 3D imaging and 3D tracking. Other mask designs can provide different functionalities. With the W-VIEW GEMINI-2C's triaxial adjustment mount and field lens unit installed, the phase masks are positioned into the relayed pupil plane. The field lens determines the macro positioning of the phase mask for each microscope system and triaxial adjustment mount provides fine x, y, z adjustment for each wavelength. With the complete W-VIEW GEMINI-2C PSF module installed, plus Double Helix phase masks and image processing software, any inverted microscope evolves into an advanced two color, 3D imaging system with super resolution capabilities. Engineered PSF imaging requires the phase masks be in the pupil plane. This is problematic since the microscope pupil plane is in the objective lens. To make engineered PSF imaging practical, it's necessary to relay the pupil plane to an accessible location. However, each microscope system has different optics, requiring flexibility in the positioning of the projected pupil plane. Hamamatsu has overcome this problem with a patent pending design that inserts a standard ield lens near the primary image plane, bringing the actual pupil plane in line with the ideal pupil plane for most microscopes and objective lenses. By choosing the appropriate focal length field lens, the phase masks (set inside the triaxial adjustment mount) align into the pupil plane. To easily visualize each phase mask, a Bertrand lens projects the pupil plane/phase mask onto the camera. All the necessary components for engineered PSF imaging are listed on inside back cover. Although not included with the W-VIEW GEMINI-2C, Hamamatsu can recommend commercially available phase masks for application and field lenses for microscope brand and configuration.
Hamamatsu Photonics K.K. Introduces New Flash4.0 V3 Digital CMOS Camera
Sep 22 16
Hamamatsu Photonics K.K. has introduced the new ORCA-Flash4.0 V3 digital CMOS camera. This one camera expertly handles applications ranging from the acquisition of beautiful scientific images to experiments that demand detection, quantification and speed. With on-board FPGA processing enabling intelligent data reduction, highly refined in-camera, pixel-level calibrations, increased USB3.0 frame rates, purposeful and innovative triggering capabilities, patented lightsheet read out modes and individual camera noise characterization the ORCA-Flash4.0 V3 is the precision instrument for imaging. ORCA-Flash4.0 cameras have always provided the advantage of low camera noise. In quantitative applications, like single molecule and super resolution imaging, fully understanding camera noise is also important. Every ORCAFlash-4.0 V3 is carefully calibrated, as a precision instrument must be. Attention to this detail delivers outstanding linearity, especially at low light, and offers improved photo response non-uniformity (PRNU) and dark signal nonuniformity (DSNU) to minimize pixel differences and reduce fixed pattern noise. Each camera ships with a certificate providing the read noise and photoelectron conversion factor specific for that camera. Like its predecessors, each ORCA-Flash4.0 V3 is capable of both USB3.0 or Camera Link output. In addition, the ORCAFlash-4.0 V3 offers data reduction through user-controllable look up tables (LUT) for 12 or 8-bit output. These two choices, combined with region of interest selection enable to fine tune acquisition speed and image data requirements. The ORCA-Flash4.0 V3 includes now patented, Lightsheet Readout Mode which takes advantage of sCMOS rollingshutter readout to enhance the quality of lightsheet images. When paired with W-VIEW GEMINI image splitting optics, a single ORCA-Flash4.0 V3 camera becomes a powerful dual wavelength imaging device.
