SW-822BS Pointed Tip Precision Polyester Swab

Product Overview

The SW-CCD-24 is a V-shape lens microfiber swab with a 24mm wide ultra-fine microfiber head sized for single-pass edge-to-edge cleaning of full-frame camera sensors (36mm × 24mm), designed for photographers and imaging professionals working with full-frame DSLR and mirrorless camera systems who require a sensor cleaning tool that matches the 24mm short dimension of the full-frame sensor format exactly. The 24mm head width allows one lateral wipe stroke to cover the full sensor height from edge to edge without the partial-coverage and streak risk that narrower swabs create when multiple overlapping passes are required on a full-frame sensor surface. Compatible full-frame camera systems include Sony Alpha A7 and A9 series (A7R V, A7C II, A9 III), Nikon Z series full-frame mirrorless (Z6 III, Z7 II, Z8, Z9), Canon EOS R series full-frame (R5, R6 Mark II, R3), and full-frame DSLR bodies from Nikon D series and Canon EOS 5D/6D lines.

The microfiber head measures 19mm in length, 24mm in width, and 1.5mm in thickness. The V-shape design is the defining structural feature that differentiates this model from the flat-profile SW-CCD-16: the head is formed into a shallow V-profile along its length, which means the central contact zone reaches the sensor surface before the head edges during the wipe stroke. This geometry ensures that cleaning contact initiates at the center of the sensor and expands outward toward the edges rather than making simultaneous edge-to-edge contact, which reduces the risk of edge-lifting the swab and introducing air bubbles under the head that cause streaking when the cleaning solution is carried unevenly across the sensor plane.

V-Shape Geometry & Microfiber Performance

The V-profile also provides a functional advantage at sensor corners and edge zones — areas where flat-head swabs frequently leave residue because the head's rigid edge cannot maintain pressure contact into the sensor corner geometry. The V-shape allows the head perimeter to flex slightly into corner areas, maintaining wiping contact to the edge of the active sensor area rather than bridging across the last millimeter. This is particularly relevant on full-frame sensors where the imaging area extends very close to the physical sensor border, and corner dust spots are a common outcome of inadequate edge-contact during cleaning.

The ultra-fine microfiber surface lifts and captures dust particles, fingerprint oils, and airborne particulates through the microfiber's characteristic sub-micron-scale fiber structure, carrying contaminants into the fiber matrix rather than redistributing them across the sensor surface. Good liquid absorption performance enables even distribution of sensor cleaning solution across the full 24mm width in a single stroke, minimizing solvent residue after evaporation. Handle dimensions: 123mm total length, 5.6mm width, 2.4mm thickness. Packaged as 1 piece per individually sealed package.

Camera Compatibility & Optical Applications

The SW-CCD-24 is the correct sensor cleaning swab for all full-frame format interchangeable lens cameras where the sensor short dimension is 24mm, including the complete Sony Alpha full-frame lineup, Nikon FX and Z full-frame bodies, Canon EOS full-frame DSLR and EOS R mirrorless bodies, Panasonic Lumix S series, Leica SL and M series digital, and Sigma fp. Beyond camera sensor cleaning, the 24mm head width applies to industrial full-frame imaging systems, high-resolution machine vision cameras, and scientific imaging sensors in astronomical and laboratory instruments where the active area matches the 24mm dimension. The V-shape head also suits telescope eyepiece lens cleaning, large-diameter objective lens surface maintenance, and precision optical flat glass cleaning where the curved-edge contact geometry reduces streaking compared to flat-profile swabs. Packaged as 1 piece per individual sealed package to guarantee cleanliness at the point of use.
