Prior Scientific Arc Lamp Light Sources
BioVision Technologies offers the following range of Prior Scientific arc lamp illumination products for brightfield and fluorescence microscopy applications:
Lumen 200PRO and Lumen 220 Pro Fluorescence Illumination Systems with Integral Filter
The Prior Scientific Lumen 200PRO and Lumen 220 Pro Fluorescence Illumination Systems combine Prior’s proprietary 2,000 hour life, 200‐watt metal arc lamp with an integral high‐speed motorized filter wheel and high‐speed motorized light attenuator.
Designed to mount remotely via a liquid light guide, the Lumen 200PRO and Lumen 220Pro eliminate heat transfer to the microscope, minimizing thermal drift and aiding image stability in long term experiments.
The Lumen 220Pro provides extended wavelength in ultraviolet and infrared. This produces significant increases in signal strength from fluorophores that require light at 360 nm and below.
Key Features of the Lumen 200Pro and Lumen 220Pro
- 2,000 hour life, 200‐Watt metal arc lamp
- Remote mounting with two‐meter or three‐meter liquid light guide
- Stabilized DC power supply for consistent illumination
- Quiet operation suitable for laboratory use
- Easy‐to‐view display screen for bulb life indication and alarm description
- Knurled light guide clamping knob for secure light guide installation
- Adapters available for all modern research microscopes
- Pre-aligned bulb for easy bulb replacement
- Integral high‐speed motorized six‐position 25 mm diameter filter wheel
- High‐speed motorized light attenuator, 0‒100% in 1% increments
- Compatible with ProScan™ and OptiScan™ controllers
Lumen 200 and Lumen 220 Fluorescence Illumination Systems
The Lumen 200 Fluorescence Illumination System is a powerful, cost‐effective alternative to standard 100 Watt mercury and halogen lamphouses. The combination of Prior’s proprietary 2,000 hour life, 200‐watt metal arc lamp and two‐ or three‐meter liquid light guide provide unrivalled versatility and illumination power. The Lumen 200 utilizes a metal halide lamp rather than the more traditional high‐pressure mercury or xenon burners. This means 2000 hours of stable output compared to a maximum of 300 hours for a mercury lamp. Coupled to the microscope using a liquid light guide there is very little heat transfer helping to eliminate thermal drift during time lapse experiments. The Lumen 200 also incorporates a variable light attenuation control to reduce the potential of bleaching and phototoxicity.
The Lumen 220 model offers extended transmission in ultraviolet and infrared. This produces significant increases in signal strength from fluorophores that require light at 360 nm and below.
Key Features of the Lumen 200 and Lumen 220
- 2,000 hour life, 200‐Watt metal arc lamp
- Remote mounting with two‐meter or three‐meter liquid light guide
- Stabilized DC power supply for consistent illumination
- Quiet operation suitable for laboratory use
- Easy‐to‐view display screen for bulb life indication and alarm description
- Knurled light guide clamping knob for secure light guide installation
- Adapters available for all modern research microscopes
- Six‐position adjustable aperture/intensity knob for protection of samples from photobleaching
- Easy bulb replacement
Lumen 200S and Lumen 220S Fluorescence Illumination Systems
The Lumen 200S is a powerful, cost‐effective alternative to standard 100 Watt mercury and halogen lamphouses. With a minimum exposure time of 30 milliseconds, the Lumen 200S is suitable for the most demanding imaging applications. A wide variety of control options are available for the Lumen 200S including RS232, USB, TTL and via the ProScan III shutter port. Designed to mount remotely via a two‐ or three‐meter liquid light guide the Lumen 200S eliminates heat transfer to the microscope, minimizing thermal drift and aiding image stability in long term experiments.
The Lumen 220S model offers extended transmission in ultraviolet and infrared. This produces significant increases in signal strength from fluorophores that require light at 360 nm and below.
Key Features of the Lumen 200S and Lumen 220S
- 2,000 hour life, 200‐Watt metal arc lamp
- Remote mounting with two‐meter or three‐meter liquid light guide
- Stabilized DC power supply for consistent illumination
- Easy‐to‐view display screen for bulb life indication and alarm description
- Knurled light guide clamping knob for secure light guide installation
- Adapters available for all modern research microscopes
- Six‐position adjustable aperture/intensity knob for protection of samples against photobleaching
- Easy bulb replacement
