The utility model discloses a small free space wavelength division multiplexer. The small free space wavelength division multiplexer comprises a ZBlock, a lens array and an optical fiber array which are arranged in sequence, according to one embodiment of the utility model, the ZBlock comprises a parallelogram substrate (parallel substrate), a rectangular prism, a plurality of filters and an anti-reflection glass sheet. A plurality of filters and an anti-reflection glass sheet are sequentially fixed on the end face, close to the lens array, of the parallel substrate side by side, and the rectangular prism is fixed on the end face, away from the lens array, of the parallel substrate. When an incident light beam is incident to the lens array from one optical fiber of the optical fiber array,the incident light beam is collimated and incident to the ZBlock, is refracted into the ZBlock through the anti-reflection glass sheet on the ZBlock, then is reflected back to the filter sheet on theZBlock through the right-
