Yokogawa CSU-W Filter Turret
Dichroic
Element type: Turret
Pos 1: VIS quad-band confocal dichroic (Di01-T405/488/568/647) — Laser-optimized confocal dichroic for the 405/488/561/640 LaserStack route (filter-turret position 1). Semrock specifies transmission at the laser lines (405, 488, 561-568, 638-647 nm) and reflection at 422-473, 503-545, 586-620, 665-750 nm; not recorded as generic pass bands here, since that would misrepresent this dichroic's reflection-side behavior in the simulator.
Pos 2: NIR short-pass confocal dichroic — Filter-turret position 2, used by both the 730 ORCA and 730 Evolve configurations. Identified locally as Chroma T750SPXR-XT-UF1; no verified transmission/reflection curve on file for this ultra-flat optic. -
CSU-W NIR Beam Combiner
Dichroic
Element type: Fixed
Details: Source-specific optic on the dedicated 730 nm NIR input before it joins the common CSU-W path; the 405/488/561/640 LaserStack lines enter through the VIS input and do not traverse this optic.
Pos 1: NIR beam combiner — Identity documented locally; no verified spectral curve or catalogue number on file. -
Widefield Dichroic
Dichroic
Element type: Fixed
Pos 1: Multiband Dichroic (FF410/504/582/669-Di01-25x36) — emission 440/40 nm, 520.5/21 nm, 606.5/34 nm, 699.5/45 nm — Semrock transmission windows: 420-460, 510-531, 589.5-623.5, 677-722 nm. -
Yokogawa CSU-W Emission Filter Wheel 1
Emission
Element type: Filter Wheel
Details: First camera-port emission wheel (10-position, per Yokogawa spec for the two-camera CSU-W1). SlideBook records both wheels as one two-digit code, e.g. 488 ORCA = 31 and 730 ORCA = 61 (wheel-1 positions 3 and 6).
Pos 1: Quad-band emitter (FF01-440/521/607/700-25) — emission 440/40 nm, 521/21 nm, 607/34 nm, 700/45 nm — Quad-band emitter for multicolor spinning-disk imaging.
Pos 2: DAPI (FF01-445/45-25) — emission 445/45 nm
Pos 3: GFP — emission 525/50 nm — SlideBook 488 ORCA configuration selects wheel-1 position 3. Previously 525/30 (FF01-525/30-25) before 2021-08-18.
Pos 4: Cy3 / Alexa 568 (FF01-617/73-25) — emission 617/73 nm
Pos 5: Cy5 / Alexa 647 (FF01-692/40-25) — emission 692/40 nm
Pos 6: Alexa 750 (FF02-809/81-25) — emission 809/81 nm — SlideBook 730 ORCA configuration selects wheel-1 position 6. -
Yokogawa CSU-W Emission Filter Wheel 2

Element type: Filter Wheel
Details: Second camera-port emission wheel (6-position, per Yokogawa spec for the two-camera CSU-W1). SlideBook's 730 Evolve code is 16 (wheel-1 position 1, wheel-2 position 6). Other wheel-2 positions are unverified and not copied from wheel 1.
Pos 6: Alexa 750 (FF02-809/81-25) — emission 809/81 nm -
