    Abstract: An array objective lens module, having an optical axis and including a substrate, multiple lens frames, and multiple objective lens sets is provided. The substrate includes multiple accommodating vias. Each accommodating via includes an internal thread structure. The lens frames are respectively disposed in the accommodating vias. Each lens frame includes an external thread structure. The external thread structure is adapted to the internal thread structure. The objective lens sets are respectively disposed in the lens frames. Each objective lens set includes at least one lens, and a relative position of each frame and the substrate in an extension direction of the optical axis changes according to a relative rotation angle of the corresponding external read structure and internal thread structure.

    Abstract: A residual toxicant detection device for testing residual toxicant in an aqueous solution is disclosed, which includes a first space cavity, a second space cavity, a connecting frame and a sensing cavity. The first space cavity includes a light source and a lens. The second space cavity includes a photo sensor and a circuit module. The connecting frame is configured to connect the first space cavity and the second space cavity. The sensing cavity for receiving an aqueous solution is formed between the first space cavity and the second space cavity and at one side of the connecting frame. The light source emits a light with a wavelength range. The photo sensor receives the sensing signal of the light passing through the sensing cavity. The circuit module is configured to calculate the absorbance and the variation in absorbance of the residual toxicants in the aqueous solution.
