* [6210H|http://www.camtech.com/products/6200/6210.html] and [6215H|http://www.camtech.com/products/6200/6215.html] are commonly used. Small and, hence, fast. Mirror sizes with clear apertures of 3,5, and 6mm are commonly used.
* The galvos are typically controlled by a pair of [671xx servo driver|http://www.camtech.com/products/servos/Servo%20Driver-671XX.html] or a dual-axis [673xx servo driver|http://www.camtech.com/products/servos/Servo%20Driver-673xx.html].

(/) To achieve the fastest scan rates supported by ScanImage over the full field-of-view in typical microscope configurations, the 'high power option' (HPO) should be specified for the servo drivers. This requires selection of the [6215H|http://www.camtech.com/products/6200/6215.html] galvo.
\\
\\
* When specifying the servo, options to use Class 0, Class 1, and (recently) 'Type 2', control topologies are offered:
** Class 0: This option has the fastest 99% settling time to step responses, but may have small residual ripple for several more time constants
** Class 1: This option has a slower 99% settling time, but has reduced ripple once it settles. This version includes an extra integrator in the control topology and strictly speaking has the possibility of instability that Class 0 avoids.
** Type 2: This is a new option offered that combines characteristics of Class 0 and Class 1
\\
\\
* Cambridge now offers galvos with 'reduced scan angle'. In typical microscope configurations, only a fraction of the galvo's scan angle is utilized to span the objective field-of-view. By selecting a reduced scan angle, a smaller mirror design with reduced inertia can be utilized for a given clear aperture.

(/) Any galvanometer with servo controller accepting an analog command waveform (in -10 to 10V range) should work with ScanImage

h4. PMTs and Associated Electronics
{panel}
* Any PMT (or other photodetector) with associated electronics producing an analog voltage signal within a unidirectional range of up to 10V can be used with ScanImage. The bandwidth of the detector and electronics should be sufficiently large to allow signal changes to occur on the order of the pixel time; otherwise, the image will be filtered.

(/) Beginning with ScanImage r3.6, ranges of 0-1, 0-2, 0-5, and 0-10V -- as well as their inverted counterparts -- can be used when digitizing the input signals.

_Commonly used combination:_
* [Hamamatsu R3896|http://sales.hamamatsu.com/index.php?id=13189363&language=1&] PMT, together with the E989 magnetic shield and E678-11A connector socket.
* [Stanford Research Systems PS310|http://www.thinksrs.com/products/PS300.htm] high-voltage power supply is used to power the PMT and control its gain level.
* [Stanford Research Systems SR570|http://www.thinksrs.com/products/SR570.htm] current preamplifier is used to amplify the PMT current signal into a measurable voltage.

* For typical Ti:S (i.e. NIR) lasers, the [350-80LA|http://www.conoptics.com/electro-optic_modulators-spcs.htm] Pockels Cell is often employed.  
* For UV/Vis lasers, the [350-50|http://www.conoptics.com/electro-optic_modulators-spcs.htm] is often used. 
* For either deflector type, the [302A|http://www.conoptics.com/electro-optic_modulators-spcs.htm] or [302RM|http://www.conoptics.com/electro-optic_modulators-spcs.htm] modulator is typically used.

(/) Any Pockels Cell system (or other light modulating system)  accepting a positive analog command waveform ranging (e.g 0-1V, 0-2V, up to 0-10V) is expected to work with ScanImage. Sufficient bandwidth is required for fast scan speeds and special features such as the _PowerBox_, _UncagingMapper_, etc.

* The [MP-285|http://www.sutter.com/products/product_sheets/MP-285.html] Stepper Motor Controller is specifically supported by ScanImage
** Special firmware options (e.g. *WD3.4*, *WD3.6*, *KS3.4*, *SA3.4*, and *VJ3.4*) are available by request from vendor. These firmware options encode, among other things, an assumed _um/step_ value in each dimension. 
** The resolution displayed on the MP-285 controller represents this _um/step_ value (in the X&Y dimensions) divided by 10 and 50, respectively, in the controller's _coarse_ and _fine_ modes.
** Firmware versions 3.4 and *WD3.4* are designed to be used with Sutter stages in all three dimensions (XY&Z). These are the standard options, i.e. without a special order.
(i) Sutter stages have a resolution of _2um/step_.
** Firmware versions *VJ3.4* and *WD3.6* are designed to use a Sutter stage in the Z dimension, but customized stages/motors in X&Y. (See section on Linear/Rotary Motor Stages for more information).
** Firmware versions *SA3.4* and *KS3.4* are designed to use customized stages/motors in XY & Z. (See section on Linear/Rotary Motor Stages for more information).
(i) _MP-285/R_ specifies order of controller alone, without associated micromanipulator

(i) No other motor controllers are supported by ScanImage at this time.

* The [XYR|http://www.dovermotion.com/StandardProductDetailPage.aspx?ID=41&Src=X-Y%20Tables] stage has been used for moving specimen stages in X/Y relative to a fixed microscope. 
* The [XYL|http://www.dovermotion.com/StandardProductDetailPage.aspx?ID=43&Src=X-Y%20Tables], [XYRB|http://www.dovermotion.com/Downloads/XYRBTable.pdf], and [XYMR|http://www.dovermotion.com/Downloads/XYMR.pdf] may also be suited for various applications.
* All of the X/Y stages consist of a lead/ballscrew and stepper motor in each dimension. Their specification includes
the *pitch* (in mm) of the lead/ballscrew and the *resolution* (in steps/revolution) of the stepper motor. Together, these determine the distance/step for the stage.
** The *SA3.4* and *VJ3.4* firmware options are designed for 0.02" pitch and 400 step/revolution motor resolution, corresponding to _1.25um/step_
** The *KS3.4* firmware option is designed for 0.02" pitch and 200 step/revolution motor resolution, corresponding to _2.5um/step_
** The *WD3.6* firmware option is designed for 2mm pitch and 400 step/revolution motor resolution, corresponding to _5um/step_

h6. [Vexta Stepper Motors|http://www.orientalmotor.com/products/ac-dc-step-motors/]
* [PK 2-Phase Stepper Motors|http://www.orientalmotor.com/products/pdfs/C_VEXTA/St2Intro.pdf] commonly used for actuating a rotary Z-focus control (e.g. microscope focusing knob)
** Standard resolution (1.8 deg/step or 200 steps/rev) option typically selected, e.g. PK266-01A
** *KS3.4* and *SA3.4* MP-285 firmware options are configured for _0.5um/step_ in Z direction. This is correct calibration for PK standard resolution steppers combined with Olympus BX microscope focusing mechanism.

* The [MOM Microscope|http://www.sutter.com/products/product_sheets/MOM.html] arranges the 3 standard [MP-285|http://www.sutter.com/products/product_sheets/MP-285.html] linear stages into an assembly for translating a microscope objective lens.
** Intended for _in vivo_ microscopy applications
** The MP-285 controller's *WD* firmware option should be used with the native MP-285 linear stages

h6. [Vincent Associates|http://www.uniblitz.com]
* [LS Laser Shutters|http://www.uniblitz.com/laser-shutters.aspx] are often used for the laser shutter, in the 2/3/6mm options depending on the laser beam size (at the shutter's location).
** For high NIR laser powers, the _ZM_ shutter blade options are often selected. E.g. the _LS6ZM2_ might be selected.
** The [VCM-DM1|http://www.uniblitz.com/product/VCM-D1%20Single%20Channel%20CE/UL/CSA%20Approved%20Shutter%20Driver.aspx], [VMM-D3|http://www.uniblitz.com/product/VMM-D3%20Three%20Channel%20Shutter%20Driver.aspx], and [VMM-D4|http://www.uniblitz.com/product/VMM-D4%20Four%20Channel%20Shutter%20Driver.aspx] shutter controllers can all be used
** (i) ScanImage only provides computer control of one of the shutters, even if using a multi-shutter controller (e.g. VMM-D3 or VMM-D4).

* [SH05|http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=927&pn=SH05] and [SC10|http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=927&pn=SH05] have also been employed
