Integrated Optics
As the only sperm analysis system with an internal optical system, the IVOS offers distinct advantages to the sperm analysis laboratory. In contrast to the continuous illumination of a microscope, the IVOS uses illumination strobed at 1/1000 of a second to visualize sperm motion. This strobed illumination eliminates motion-related blurring along the length of the sperm head, resulting in precise sperm tracking. By adding an image capture rate of 60 frames per second, you get the highest level of accuracy available today for measuring sperm velocities and motion parameters. For added flexibility, the IVOS performs analyses under three types of internal, strobed illumination: phase contrast, bright field and multi-wavelength fluorescence.
As part of the integrated optical system, the unique computer controlled specimen stage of the IVOS provides precise control of temperature and position during analysis. The stage temperature, which may be set from ambient to 40°C, remains constant to within 0.5°C. For selection of analysis fields, the stage may be programmed for either manual or automatic field selection. For at-a-glance monitoring, the current stage temperature and position are continuously shown on screen as a real-time, digital display. The IVOS stage accommodates and automatically adjusts for commonly used analysis chambers, such as disposable fixed-depth slides, cannulas and Makler chambers. In addition, a user-defined chamber setting is available
The IVOS hardware and software have been designed to provide users with a system that offers high-end performance while maintaining its ease of use. The intuitive Windows-based software promotes fast learning and quickly increases the confidence level of users. Since the settings for the integrated optics are made through the software, mechanical adjustments are rarely required. With a minimum investment of time, even users unfamiliar with computers will be performing fast, accurate and reliable sperm analyses. You dont need to be a computer expert to analyze sperm with the IVOS.
Redesigned software interface of Version 12 makes operation intuitive
Up to 7 analysis setups (including optic calibrations) may be stored to memory and selected at the touch of a button
Patient and sample information easily entered from keyboard
Simply place the sample chamber on the stage, focus the image, select the fields, and begin analysis
On-site customized installation and training provided with all new systems
Whether you need basic counts and motilities or detailed analysis of sperm motion, the IVOS provides you with the results you need. Results for motile, progressively motile and static sperm include actual number counted, sample total, concentrations and percentages. Additional results include averages and distribution bar charts of velocities, motion characteristic and morphometry.
The IVOS provides on demand quality control with the Playback feature. Using image Playback, the accuracy of the analysis is confirmed. To optimize the system, analysis parameters may be adjusted using the two interactive QC Plots or directly from the analysis setup screen.
Because of its ease of use and high levels of quality control, the IVOS has been awarded a rating of moderately complex by CLIA. This means fewer restrictions for you lab!
