Equal-Height Mount with Base MQC-1A

JCOPTIX equal-base, equal-height mounts work directly or with matching optical mounts to produce a uniform 50 mm optical-axis height. Four types—25 mm posts with square bases, 25 mm posts with clamp slots, cage plates with bases, and lens mounts with bases—require MQB-6090 unanodized standard breadboards for optical systems maintaining a 50 mm axis throughout. Square-base 25 mm posts. Models: MQP1-25A, MQP1-36A, MQP1-38A, MQP1-50CA. Top mounting holes; square bases mount directly to MQB-6090 unanodized breadboards; matching mounts produce 50 mm axes. JCOPTIX 25 mm posts are one-piece solid nonmagnetic stainless steel with fine bead blasting for strength/rigidity. Top holes accept matching mounts. Four M4 smooth straight U-slots at the base accept M4 cap screws to attach the 25 mm post directly to MQB-6090 unanodized breadboards. MQP1-25A, MQP1-36A, and MQP1-38A have auxiliary top bosses for 45° mount installation. Three boss-equipped 25 mm post heights are available. MQP1-25A has a 24.6 mm mounting height and two M4 top holes at different distances from the boss, fitting round two-axis mounts with 25.4 mm optical-axis height or Ø25.4 mm stainless mounts for a 50 mm final axis. MQP1-36A is 35 mm high, with an M4 threaded and M4 countersunk hole, fitting round two-axis mounts with 15 mm axes for a 50 mm final axis. MQP1-38A is 37.3 mm high with two M4 top holes, fitting Ø12.7 mm stainless mounts for a 50 mm final axis. MQP1-50CA has three top M3 countersunk holes and three supplied M3×4 cap screws. Its central through-hole axis is 50 mm above the bottom, fitting 0.5-inch vertical flexure mounts for a 50 mm final optical axis. Users can build appropriate paths; the relatively low 50 mm axis improves overall stability. Clamp-slot 25 mm posts. Models: MQP1-25B, MQP1-35B, MQP1-38B. Top M4/bottom M6 threads; slots for MQB-20 fork clamps; matching mounts produce 50 mm axes. These JCOPTIX 25 mm posts are one-piece solid nonmagnetic stainless steel, finely blasted for strength/rigidity. Top M4 holes and two Ø2 mm dowel holes provide precise location; an M4×12 socket set screw is included. Bottom slots require MQB-20 fork clamps. A side through-hole accepts a hex key for greater tightening torque. Three 25 mm post heights are available: MQP1-25B, mounting height 24.6 mm plus a 25.4 mm-axis mount gives 50 mm; MQP1-35B, 35 mm plus a 15 mm-axis mount gives 50 mm; MQP1-38B, 37.3 mm plus a 12.7 mm-axis mount gives 50 mm. Users can build suitable paths; the relatively low 50 mm axis improves stability. Cage plate with base. Model: MQC-1A. Standalone mounting at 50 mm axis; Ø25.4 mm optics; rubber-tip screw fixation. Two bottom M4 elongated slots attach directly to MQB-6090 unanodized breadboards at a 50 mm axis. Ø25.4 mm optics are held by a top M4 rubber-tip screw and a two-line locating bore. Compatible with 30 mm cages. Stainless lens mounts with bases. Models: MQM-05B, MQM-1A, MQM-1B. Direct M4 smooth-bore mounting for 50 mm axes; Ø12.7 mm or Ø25.4 mm optics; flexure springs; 45° optic orientation. Supplied M4*10 screws attach directly to MQB-6090 unanodized breadboards at a 50 mm axis. One-piece solid nonmagnetic stainless steel with fine blasting provides strength/rigidity. Flexure springs secure Ø12.7 mm or Ø25.4 mm optics at 45°.
