A digital slide-scanning stage comprising: a fixed portion having a first top surface and a first slide surface recessed below the first top surface by a first side surface, wherein the first slide surface is configured to support a bottom portion of a glass slide ; a movable portion having a second top surface and a second slide surface recessed below the second top surface by a second side surface, wherein the second slide surface is configured to support a bottom portion of a glass slide; and a base ; wherein the second side surface of the movable portion opposes the first side surface of the fixed portion to form a recess above the first and second slide surfaces, wherein the movable portion is configured to move between at least a first position, having a first distance from the fixed portion, and a second position, having a second distance from the fixed portion, such that, in the first position, the first and second side surfaces and the first and second slide surfaces form a first recess of a first size configured to hold a glass slide having a first width dimension, and, in the second position, the first and second side surfaces and the first and second slide surfaces form a second recess of a second size configured to hold a glass slide having a second width dimension that is different than the first width dimension, wherein the fixed portion comprises a fixed arm extending from the base in a first direction, and wherein the movable portion comprises a movable arm extending in the first direction and configured to slide in a second direction that is orthogonal to the first direction, so as to change a distance between the fixed arm and the movable arm wherein the base comprises a rail extending linearly in the second direction, and wherein the movable arm is configured to slide along the rail in the second direction causing at least one contact point of the moveable arm to press the glass slide against at least one contact point of the fixed arm. a fixed portion having a first top surface and a first slide surface recessed below the first top surface by a first side surface, wherein the first slide surface is configured to support a bottom portion of a glass slide ; a movable portion having a second top surface and a second slide surface recessed below the second top surface by a second side surface, wherein the second slide surface is configured to support a bottom portion of a glass slide; and a base ; wherein the second side surface of the movable portion opposes the first side surface of the fixed portion to form a recess above the first and second slide surfaces, wherein the movable portion is configured to move between at least a first position, having a first distance from the fixed portion, and a second position, having a second distance from the fixed portion, such that, in the first position, the first and second side surfaces and the first and second slide surfaces form a first recess of a first size configured to hold a glass slide having a first width dimension, and, in the second position, the first and second side surfaces and the first and second slide surfaces form a second recess of a second size configured to hold a glass slide having a second width dimension that is different than the first width dimension, wherein the fixed portion comprises a fixed arm extending from the base in a first direction, and wherein the movable portion comprises a movable arm extending in the first direction and configured to slide in a second direction that is orthogonal to the first direction, so as to change a distance between the fixed arm and the movable arm wherein the base comprises a rail extending linearly in the second direction, and wherein the movable arm is configured to slide along the rail in the second direction causing at least one contact point of the moveable arm to press the glass slide against at least one contact point of the fixed arm. <EOS>
