As the leading provider of MCPs for electron multiplication, Photonis provides our MCPs in a variety of custom sizes  (4mm to 150mm) and configurations (Z-Stack or Chevron). Our extended dynamic range output option  increases detection up to ten times over traditional MCPs. Available in detection, image, and premium grades, Photonis’ MCPs are designed to provide stable gain and outstanding bias current stability. You can specify the pitch/pore size as well as the shape, size, and configuration. By partnering with Photonis for all of your MCP needs, you will get a detector exactly suited to your needs.

MountingPad™ Technology

MountingPad™ MCPs are rimless microchannel plates which have been patented to prevent excessive noise due to trapped gas or damaged pores near the edges from mounting the MCP. Our MountingPad™ technology provides a rigid area to attach the MCP without damaging pores, yet provides a gap between the active channels and the mounting hardware. This gap allows gas to vent, eliminating plasma discharges which cause excessive noise.

Improving TOF-MS Instruments Using TruFlite™ MCP

Photonis’ TruFlite™ microchannel plates provide a clear advantage to competitors’ products. Their superior flatness reduces time jitter and ion arrival time, as demonstrated below. If you are looking to improve the results of your TOF-MS instrument, upgrade your detector to include a TruFlite™ MCP.




TruFlite™ Microchannel Plate

trufliteUsed in Time of Flight Mass Spectrometry, these microchannel plates have been manufactured to control input surface flatness to +/- 5 microns in order to reduce ion arrival time jitter.

TruFlite™ microchannel plates are designed to control and optimize two common errors in Time of Flight Mass Spectrometry - ion arrival time and time jitter. As the manufacturer, Photonis is able to provide these detectors as standalone pieces or as part of our Gen2 UltraFast TOF detector assembly. 
TruFlite™ MCPs are available in 18mm sizes with a bias angle of 19o and a 2µm pore size, or a 25mm or 40mm MCP with a bias angle of 19o and a 5µm pore size. Typical flatness can be controlled at the time of manufacture to within 10µm across an MCP. (Note that 2µm MCPs are not sold individually but can be ordered in complete Gen2 UltraFast™ TOF assemblies.)

Stripline Microchannel Plate

striplineMCPThese microchannel plates have been lined with several layers of electroding material to sequentially capture high-speed charged particle events. Stripline MCPs are ideal for high energy physics research when documenting or diagnosing the sequence of high-speed occurrances.

Stripline MCPS are capable of capturing sequential images of charged particle events at very high speeds, making them extremely useful diagnostic tools for documenting nuclear events during energy research and process development. Stripline MCPs use electrode strips to create dielectric polarization, allowing for the movement of ions toward or away from a positive or negative charge. The result is that each individual microchannel within the MCP can be turned on or off sequentially as fast as the electrical charge can permeate the circuit.

Stripline MCPs are made with image grade microchannel plates, using the patented MountingPad™ technology to minimize warping and cracking while allowing trapped plasma gasses to vent, eliminating noise. Pitch, pore, and bias angle can be specified.

Glass Capillary Arrays

glass-capillary-arraysGlass Capillary Arrays consist of millions of precision glass capillary tubes fused together to produce a uniform and mechanically rigid structure. They can be used for sample filtration, collimation or as optical beam line splitters. They can be made into custom sizes and shapes to best fit your requirement.
Photonis Glass Capillary Arrays have exceptional thermal and chemical stability, and can be manufactured to withstand temperatures in excess of 450°C for use in harsh environments.

It can be provided with a ground matte finish or a polished service. The input surface can also be blackened to minimize light scattering. Solid border Glass Capillary Arrays are compatible with most existing Millipore or Nuclepore equipment, or fitted within a metal flange or mounted on glass tubing for high temperature or high pressure applications.
