The speed, the price (about $525 online), the high resolution (six megapixels), the optional auxiliary lenses (a $30 adapter is required) and the PC sync port (for attaching an external flash) all suggest that Casio is aiming for a more sophisticated shutterbug.
The spectrometer is designed to allow for retardation of the pass energy without the need to incorporate auxiliary lenses.
Other setups for retina imaging and documentation use auxiliary aspheric lenses in combination with retina cameras [ 25] or slit lamps [ 26] that show inhomogeneous fundus illumination and low-contrast imaging, respectively.
Using SoftWoRx 3.7.0 Release 13EL (Applied Precision), FISH signals were detected on an IX70 microscope (Olympus) controlled by a Deltavision System (Applied Precision, ×60 1.4 oil objective lens, auxiliary magnification of 1.5 and optical step size of 0.2 μm) and analyzed in the z section with the brightest signal intensity.
Conditions for electrospray were as follows: positive ion mode; needle voltage 1.9 kV; no sheath and auxiliary gas flow; tube lens voltage 45 V; and capillary temperature 250°C.
Each module consists, in sequence, of a high contrast cross target placed at the focal point of a +13.3 D collimating lens (FC), an auxiliary +6.7 D lens (FA) and a +13.3 D Badal lens (FB).
MS conditions [spray voltage-3700 V, ion transfer capillary temperature 270°C, source temperature 30°C, sheath gas 20, auxiliary gas 10 (arbitrary units), collision gas-argon, S-lens voltage and collision energy were optimized for individual amino acids, scan time-50 millisec, ion polarity is positive).
