Lighting subsystems to drive 21st century bioanalysis and biomedical diagnostics face stringent requirements. Industrywide
demands for speed, accuracy and portability mean illumination must be intense as well as spectrally pure,
switchable, stable, durable and inexpensive. Ideally a common lighting solution could service these needs for numerous
research and clinical applications. While this is a noble objective, the current technology of arc lamps, lasers, LEDs and
most recently light pipes have intrinsic spectral and angular traits that make a common solution untenable. Clearly a
hybrid solution is required to service the varied needs of the life sciences.
Any solution begins with a critical understanding of the instrument architecture and specifications for illumination
regarding power, illumination area, illumination and emission wavelengths and numerical aperture. Optimizing signal to
noise requires careful optimization of these parameters within the additional constraints of instrument footprint and cost.
Often the illumination design process is confined to maximizing signal to noise without the ability to adjust any of the
above parameters. A hybrid solution leverages the best of the existing lighting technologies. This paper will review the
design process for this highly constrained, but typical optical optimization scenario for numerous bioanalytical
instruments and biomedical devices.
Light is a powerful tool for the life sciences. High intensity, low cost light engines are therefore essential to the design and proliferation of new bioanalytical instruments, medical devices and miniaturized analyzers. Lumencor has developed an inexpensive lighting solution, uniquely well suited to the production of safe, effective, commercial life science devices. Lumencor’s proprietary technology provides powerful, pure, stable, inexpensive light across the UV-Vis-IR. Light engines are designed to directly replace the entire configuration of light management components with a single, simple unit. Multicolor prototypes will be discussed and their performance capabilities disclosed.
This paper presents an update on the progress to commercialize a new, unique replacement for the powder phosphor currently used in projection cathode ray tubes (CRTs). The new display technology designated Resonant Microcavity Phosphor display (RMP), is now being tested for use in CRTs similar to those currently used in commercial rear projection televisions. This new technology allows resolution, brightness and dynamic range well beyond what is possible with current powder phosphor approaches. Recent test data on operational red, blue and green RMPs faceplates will be presented. Additionally, this paper gives engineers a basic understanding of the characteristics and advantages of the RMP display technology. Some of the key reasons for the need for a new phosphor for the projection CRT are presented. Current and future RMP Display performance is presented. Another future application for RMP technology is as a narrow-band electronically addressable light source, an economical replacement for laser scanning. The technology also has many other applications where a uniform, large area, narrow-band light source or confined beam (non-Lambertian), electron excited light generation is required.
