The phrase "accurately focused" is correct and usable in written English.
You can use it to describe something that is precisely directed or concentrated on a specific subject or goal.
Example: "The research was accurately focused on the impact of climate change on local ecosystems."
Alternatives: "precisely targeted" or "sharply concentrated".
The big technological challenge in the optical tape program was to keep the material at the proper tension when traveling at high speeds so that the laser could be accurately focused.
The present paper demonstrates that the cellular response on a Ti surface could be enhanced through surface treatment by an accurately focused beam of a low-power pulsed Nd YAG laser.
To obtain the nanopatterns with high precision and consistency, the focal sphere should be accurately focused onto the surface of the photoresist.
The lethal hit delivered by releasing the contents of perforin-containing secretory lysosomes needs to be accurately focused on the target cell alone.
For efficient separation based on differential equilibrium positions two conditions must be met: (1) both the selected and unselected particles must be accurately focused, and (2) their equilibrium positions must be different.
In this configuration, individual crystals can be inspected, the z height fine-tuned for eucentricity, and the center spot accurately focused by minimizing the size of the spot of the direct beam at a dose rate <10−3 e Å−2 s−1.
Hence, the present three-scale method can accurately focus on the behaviors at arbitrary scale differently from the conventional hierarchical model.
Stereotaxic surgery uses a three-dimensional system of coordinates obtained by X-ray photography to accurately focus high-intensity radiation, cold, heat, or chemicals on tumours located deep in the brain that could not otherwise be reached.
The 16MP PixelMaster main camera has a f/2.0 aperture lens with a phase-detection autofocus (PDAF) system that can accurately focus on a subject in just 0.03 seconds.
It does so, it seems, ideally by the educational means that a dialectician would use — by accurately focusing the discussion onto the object of inquiry, in this case man, and thus helping interlocutors to proceed with the task of defining, and thereby understanding, what a man essentially is.
The number of phase detection pixels on the X-T30's X-Trans CMOS 4 image sensor has been increased to 2.16 million, about four times more than its predecessor, the X-Trans CMOS 3. The on-sensor phase detection AF area now covers the whole of the frame (approx. 100%), making it possible to quickly and accurately focus on a subject wherever it is in the frame.
